History of Spreadsheet Software: Evolution, Major Programs, Versions, File Formats and Their Rise and Fall

Quick Answer

Spreadsheet software is an application used to organize, calculate, analyze and present information in rows and columns. Its history began with early computerized financial planning systems in the 1960s, followed by the introduction of VisiCalc in 1979, the first widely recognized spreadsheet program for personal computers.

During the 1980s, VisiCalc, Lotus 1-2-3, Microsoft Multiplan, SuperCalc and Quattro Pro competed for users. Microsoft Excel, first released for the Apple Macintosh in 1985 and later for Windows in 1987, gradually became the leading spreadsheet application. In the 2000s, web-based services such as Google Sheets introduced real-time collaboration and cloud storage. Today, Microsoft Excel, Google Sheets, Apple Numbers and LibreOffice Calc are among the widely used spreadsheet applications.

The evolution of spreadsheet software reflects major changes in computing, including the transition from personal computers to graphical interfaces, office productivity suites, open-source software, cloud computing, mobile devices and artificial intelligence.

What Is Spreadsheet Software?

Spreadsheet software is a type of application software designed to store, organize, process and analyze information in a tabular format. A spreadsheet consists of rows and columns, and the intersection of a row and column is called a cell.

Each cell can contain numbers, text, dates, formulas or other types of information. Formulas allow users to perform calculations automatically using data stored in other cells.

For example, a business can use spreadsheet software to maintain customer records, calculate sales, prepare financial reports, manage inventory, track employee attendance and prepare budgets.

Modern spreadsheet applications offer much more than calculations. They support charts, data analysis, pivot tables, automation, data validation, external data connections, collaboration and reporting.

Early History of Electronic Spreadsheets

Before computer-based spreadsheet applications became popular, businesses maintained financial records and calculations using paper worksheets, accounting books and mechanical calculators.

Although these methods were useful, changing one value often required manually recalculating several other figures. This made complex financial planning time-consuming and increased the possibility of calculation errors.

1961–1964: Early Concepts of Computerized Spreadsheets

Economist Richard Mattessich made important contributions to the concept of computerized budgeting and spreadsheet models. His research on budgeting models and computer-based simulation during the early 1960s helped establish the theoretical foundation for electronic spreadsheets.

His work demonstrated how financial models could be represented through interconnected numerical calculations and processed by computers.

1969–1970: LANPAR

LANPAR, short for Language for Programming Arrays at Random, was an early electronic spreadsheet system associated with business planning and budgeting applications.

It introduced the idea of allowing users to work with interconnected numerical tables without manually rewriting an entire program whenever the structure of a financial model changed.

LANPAR was an important development in the history of electronic spreadsheet technology, although it was not a mass-market personal computer application like the products that followed.

Major Spreadsheet Software: Their History, Success and Decline

Several spreadsheet applications helped shape the modern software industry. Some became highly successful, while others lost market share because of competition, platform changes, limited development or changes in user requirements.

1. VisiCalc (1979)

Developer: Dan Bricklin and Bob Frankston

Company: Software Arts, initially distributed by Personal Software, later known as VisiCorp.

Initial platform: Apple II

First release: October 17, 1979

VisiCalc is widely recognized as the first commercially successful electronic spreadsheet application for personal computers. Its name came from the expression "Visible Calculator".

Dan Bricklin conceived the idea while studying at Harvard Business School. He wanted a computer program that would allow users to enter numbers into a visible grid and automatically recalculate related results when a value changed.

Working with programmer Bob Frankston, he developed the application that transformed this concept into a practical business tool.

Important Features

• Rows and columns for organizing information.
• Cell-based calculations.
• Formulas using cell references.
• Automatic recalculation when input values changed.
• Support for financial planning and budgeting.
• Ability to save and retrieve spreadsheet data.

Why Was VisiCalc Successful?

VisiCalc gave personal computers a practical business purpose. Instead of being used mainly for programming and technical experimentation, computers could now perform financial calculations and business planning.

Businesses and professionals purchased Apple II computers partly because they wanted to use VisiCalc. It became an example of a killer application: software so useful that people purchased the computer specifically to run it.

Why Did VisiCalc Lose Its Market Position?

VisiCalc eventually lost its leading position to Lotus 1-2-3.

Some important factors were:

• Lotus 1-2-3 offered more integrated features.
• Lotus made effective use of IBM PC hardware.
• Competition increased rapidly during the early 1980s.
• Business users increasingly preferred newer applications with charting, data handling and automation capabilities.
• Corporate and legal difficulties affected the VisiCalc business.

Lotus acquired Software Arts in 1985 and discontinued VisiCalc in favor of its own spreadsheet product.

Historical importance: Although VisiCalc did not survive as a leading commercial product, its basic spreadsheet concept became the foundation of modern spreadsheet applications.

2. SuperCalc (1980)

Developer: Sorcim

Initial platform: CP/M-based personal computers

Initial release: 1980

SuperCalc was one of the important spreadsheet applications that followed VisiCalc. It was developed for the growing personal computer market and became particularly relevant among CP/M computer users.

The software later received several versions, including SuperCalc3 and SuperCalc5, which expanded its capabilities.

Important Features

• Spreadsheet-based calculations.
• Financial and business modelling.
• Multiple spreadsheet functions.
• Improved worksheet management in later versions.
• Three-dimensional spreadsheet capabilities in later releases.

Why Did SuperCalc Lose Popularity?

SuperCalc faced increasing competition from Lotus 1-2-3 and Microsoft Excel. As IBM-compatible computers became more common, businesses increasingly selected applications with stronger market support, compatibility and development ecosystems.

The product's historical importance remains significant, even though it did not maintain its earlier market position.

3. Microsoft Multiplan (1982)

Developer: Microsoft

Initial release: 1982

Platforms: CP/M, Apple II, MS-DOS and other supported systems.

Before Excel became Microsoft's major spreadsheet application, the company developed Multiplan.

Multiplan was designed to work across multiple computer platforms, which was an important strategy when different operating systems and hardware architectures were common.

Why Was Multiplan Important?

• It established Microsoft's presence in the spreadsheet market.
• It supported business calculations and financial models.
• It was available on several computer platforms.
• It provided Microsoft with experience in developing spreadsheet applications.

Why Did Multiplan Lose to Lotus 1-2-3?

Lotus 1-2-3 became more attractive to many IBM PC users because of its integrated capabilities and strong performance on that platform.

Multiplan's interface and command structure also made it less appealing to some users compared with competing applications.

Microsoft eventually shifted its spreadsheet strategy toward Excel, which offered a more graphical and accessible experience.

4. Lotus 1-2-3 (1983)

Developer: Lotus Development Corporation

Key developers: Mitch Kapor and Jonathan Sachs

Initial release: January 26, 1983

Initial platform: IBM PC and compatible DOS computers

Lotus 1-2-3 became one of the most influential business applications of the 1980s. It was named after its three major capabilities: spreadsheet calculations, graphics and database functionality.

It improved upon the spreadsheet experience established by VisiCalc and made personal computers considerably more useful for business users.

Important Features

• Spreadsheet calculations and formulas.
• Integrated charting and graphics.
• Database and data management functions.
• Macro capabilities for automating repetitive tasks.
• Business reporting and financial modelling.
• Performance optimized for IBM-compatible PCs.

Important Lotus 1-2-3 Versions

Version or Generation	Period	Significance
Lotus 1-2-3 Release 1	1983	Original DOS release.
Release 1A	1980s	Updated the original application.
Release 2.x	1980s	Expanded spreadsheet functionality and capabilities.
Release 3.x	Late 1980s	Introduced major improvements, including expanded worksheet capabilities.
Lotus 1-2-3 for Windows	1990s	Adapted the product to graphical Windows environments.

This is a summary of important product generations, not an exhaustive version-by-version release register.

Why Was Lotus 1-2-3 So Successful?

Lotus 1-2-3 benefited from the growing popularity of IBM-compatible personal computers. It was fast, feature-rich and suitable for business calculations, financial planning and reporting.

It also developed a strong ecosystem of trained users, consultants, business templates and supporting applications.

Why Did Lotus 1-2-3 Decline?

Microsoft Excel gradually became a stronger competitor as Windows became the dominant desktop operating environment.

Important reasons for the decline included:

• Excel offered a graphical interface suited to Windows.
• Microsoft Office became increasingly popular in businesses.
• Excel benefited from integration with Word and PowerPoint.
• Lotus struggled to maintain the same competitive momentum in the changing desktop environment.
• Businesses increasingly preferred software with strong long-term development and support.

IBM acquired Lotus Development Corporation in 1995. Lotus 1-2-3 continued to receive support and updates for years, but its commercial importance declined as Excel became the dominant desktop spreadsheet.

IBM announced the withdrawal of support for Lotus SmartSuite and related Lotus products, including Lotus 1-2-3, effective September 30, 2014.

Historical importance: Lotus 1-2-3 helped establish spreadsheet applications as essential business software and played an important role in the success of IBM-compatible PCs.

5. Microsoft Excel (1985)

Developer: Microsoft Corporation

First release: September 30, 1985

Initial platform: Apple Macintosh

First Windows release: Excel 2.0, 1987

Microsoft Excel is one of the most successful and widely used spreadsheet applications in computing history.

Interestingly, Excel was initially released for Apple Macintosh computers rather than Windows. The Macintosh offered a graphical user interface and mouse-based interaction, allowing Microsoft to develop a more visually interactive spreadsheet experience.

Excel later became available for Windows, where it benefited from the growing popularity of the Windows operating system and Microsoft Office suite.

Why Did Excel Become the Market Leader?

Excel's success was not based on a single feature. Several developments contributed to its long-term position.

1. Windows became a dominant operating system for personal and business computers.
2. Microsoft Office provided a familiar collection of productivity applications.
3. Excel offered powerful calculation and analysis capabilities.
4. Businesses developed extensive spreadsheets, templates and VBA-based applications around Excel.
5. Compatibility with older Excel workbooks helped organizations continue using their existing data.
6. Microsoft maintained long-term development and introduced new features over multiple decades.

Excel also benefited from network effects: the more businesses used it, the more useful its file compatibility, training materials, templates and supporting applications became.

6. Quattro Pro (1987–1989)

Developer: Borland International

Initial development and introduction: Late 1980s

Important releases: Quattro Pro and Quattro Pro 2.0 in 1989.

Quattro Pro was a major spreadsheet competitor developed and marketed by Borland. It became popular among users looking for an alternative to Lotus 1-2-3 and Microsoft Excel.

The product was known for its spreadsheet capabilities and support for Lotus 1-2-3 compatibility, which was particularly important for businesses migrating between spreadsheet applications.

Important Features

• Spreadsheet calculations.
• Financial and business modelling.
• Charts and graphical presentation.
• Database-related functionality.
• Compatibility features for Lotus 1-2-3 users.

What Happened to Quattro Pro?

Quattro Pro changed ownership several times. Borland's spreadsheet business was acquired by Novell in 1994, and Corel acquired the WordPerfect and Quattro Pro products in 1996.

Quattro Pro subsequently became part of Corel's WordPerfect Office suite.

Although it did not achieve Excel's market dominance, it continued to serve users who preferred WordPerfect Office and its spreadsheet environment.

Reason for reduced popularity: Microsoft Excel's strong integration with Windows and Microsoft Office made it increasingly difficult for alternative desktop spreadsheet applications to compete for mainstream business users.

7. Wingz (1989)

Developer: Informix

Initial platform: Apple Macintosh

Initial release period: Late 1980s

Wingz was an advanced spreadsheet application known for its graphical capabilities and powerful analytical features.

It attempted to provide users with more sophisticated ways to create spreadsheet models, presentations and data-driven applications.

Wingz demonstrated that spreadsheet software was evolving beyond basic calculations into more advanced analytical and graphical environments.

However, it did not achieve the widespread adoption of Microsoft Excel. Platform reach, ecosystem size and Microsoft's growing dominance in desktop productivity software limited its long-term market position.

8. OpenOffice.org Calc (2002)

Project: OpenOffice.org

Initial public release of OpenOffice.org: 2002

Spreadsheet component: Calc

OpenOffice.org Calc became an important alternative to commercial spreadsheet software. It provided users with spreadsheet functionality without requiring a traditional paid Microsoft Office license.

Important Features

• Spreadsheet calculations and formulas.
• Charts and data analysis.
• Multiple worksheets.
• Support for several spreadsheet file formats.
• OpenDocument Spreadsheet support.
• Compatibility with many Microsoft Excel files.

Why Was OpenOffice.org Calc Important?

It helped expand access to office productivity software for home users, educational institutions, small businesses and organizations looking for an open-source alternative.

Its open-source nature also allowed developers to examine, modify and distribute the software according to the project's licensing terms.

What Happened to OpenOffice.org?

After Oracle acquired Sun Microsystems in 2010, the OpenOffice.org project underwent major organizational changes. The Document Foundation was established and launched LibreOffice as an independent successor project based on the existing OpenOffice.org codebase.

Apache OpenOffice later became another continuation of the OpenOffice software family under the Apache Software Foundation.

OpenOffice.org Calc is therefore a historical product name, while Apache OpenOffice Calc and LibreOffice Calc are separate continuing projects.

9. LibreOffice Calc (2010)

Developer: The Document Foundation

Initial release: 2010

Project origin: OpenOffice.org

LibreOffice Calc is an open-source spreadsheet application and one of the major alternatives to Microsoft Excel.

It supports spreadsheet calculations, data analysis, chart creation and a variety of spreadsheet file formats.

Google Sheets also helped popularize the idea that productivity applications could operate primarily through cloud services rather than traditional desktop installations.

Its limitations compared with desktop Excel may include advanced modelling requirements, certain specialized functions, large-data workloads and compatibility with complex Excel macros.

11. Apple Numbers (2007)

Developer: Apple Inc.

Initial introduction: August 2007

Platforms: macOS, iOS and iPadOS, with browser access through iCloud.

Apple introduced Numbers as part of its iWork productivity suite.

Why Some Spreadsheet Software Succeeded While Others Failed

The history of spreadsheet software provides useful examples of how technology companies compete and why established products sometimes lose their market position.

A technically capable application does not automatically become commercially successful. Adoption, compatibility, ease of use, platform support, development resources and business ecosystems are equally important.

1. Compatibility with Popular Operating Systems

Software must work well on the computer platforms used by its intended customers.

Lotus 1-2-3 benefited from its strong relationship with the IBM PC and DOS ecosystem. Excel later gained an advantage when Windows became the dominant desktop environment.

Applications that failed to adapt to changing operating systems often struggled to maintain their user base.

2. Features and Innovation

Users expect software to improve over time. Better formulas, faster calculations, graphical tools, automation and data analysis capabilities can make a product more attractive.

VisiCalc introduced the practical electronic spreadsheet experience, Lotus 1-2-3 expanded integrated business capabilities, and Excel developed into a comprehensive analysis and productivity platform.

3. User Interface and Ease of Use

The shift from command-driven environments to graphical interfaces significantly changed how people interacted with software.

Applications that made complex tasks easier to understand and perform gained an advantage among business users.

4. Integration with Other Software

Integration became an important competitive advantage.

Excel benefited from its relationship with Microsoft Word, PowerPoint, Outlook, Windows, SharePoint and other Microsoft services.

Similarly, Google Sheets benefited from its integration with Google Drive and Google Workspace.

5. File Compatibility and Data Portability

Businesses often maintain spreadsheets for many years. They may contain financial records, formulas, reports, macros and important historical information.

Switching software becomes difficult if the new application cannot correctly open or reproduce existing spreadsheets.

Applications with better file compatibility can therefore attract and retain more users.

6. Development and Customer Support

Software requires regular maintenance, security updates, bug fixes and compatibility improvements.

When a developer stops investing in a product, customers may gradually move to applications that receive more active development and support.

7. Business Ecosystem and Network Effects

Successful software often develops an ecosystem of consultants, training courses, templates, plugins, integrations and third-party applications.

Excel's large ecosystem has been an important advantage. Even when competing applications provide similar basic functions, businesses may prefer the product their employees, customers and partners already use.

8. Transition from Desktop to Cloud Computing

The growth of cloud computing changed the spreadsheet market.

Users increasingly wanted to access files from multiple devices, share them with colleagues and collaborate without exchanging attachments.

Google Sheets benefited from this transition, while Microsoft responded by expanding Excel's web, mobile and cloud-connected capabilities.

Types of Spreadsheet Software

Spreadsheet applications can be classified according to their operating environment, licensing model and intended purpose.

1. Desktop Spreadsheet Software

Desktop spreadsheet applications are installed on computers and can provide extensive functionality, including advanced calculations, large workbooks, data connections and automation.

Examples include:

• Microsoft Excel Desktop.
• LibreOffice Calc.
• Apache OpenOffice Calc.
• Apple Numbers for Mac.
• WPS Spreadsheets.

2. Cloud-Based Spreadsheet Software

Cloud-based applications operate primarily through internet-connected services. Users can access their spreadsheets through web browsers and supported applications.

Examples include:

• Google Sheets.
• Microsoft Excel for the web.
• Zoho Sheet.
• ONLYOFFICE Docs.

3. Open-Source Spreadsheet Software

Open-source spreadsheet applications provide access to their source code under their respective open-source licenses. Users and organizations can use, distribute or modify them according to the applicable license terms.

Examples include LibreOffice Calc, Apache OpenOffice Calc and Gnumeric.

4. Commercial Spreadsheet Software

Commercial applications are developed and distributed by companies that may offer paid licenses, subscriptions, business editions or additional services.

Examples include Microsoft Excel, WPS Spreadsheets and commercial spreadsheet products from other vendors.

Mobile spreadsheet applications are designed for smartphones and tablets. They allow users to view, create and edit spreadsheet documents while travelling or working away from their desks.

Examples include:

• Microsoft Excel for Android and iOS.
• Google Sheets for Android and iOS.
• Apple Numbers for iPhone and iPad.
• WPS Office mobile applications.

Important Spreadsheet File Formats and Their Extensions

Spreadsheet file formats define how information is stored inside a spreadsheet document. They determine how cells, formulas, formatting, worksheets, charts, macros and other workbook components are represented.

Different spreadsheet applications support different file formats. Understanding these formats is important when exchanging documents between software products.

Extension	Full Name or Description	Common Use
.XLS	Microsoft Excel Binary Workbook	Legacy Excel workbook format, particularly Excel 97–2003.
.XLSX	Office Open XML Spreadsheet	Modern default Excel workbook format.
.XLSM	Excel Macro-Enabled Workbook	Excel workbook supporting VBA macros.
.XLSB	Excel Binary Workbook	Binary workbook format supporting advanced Excel functionality and macros.

.QPW	Quattro Pro Workbook	Corel Quattro Pro spreadsheets.
.NUMBERS	Apple Numbers Document	Native Apple Numbers spreadsheet documents.
.GSHEET	Google Sheets Drive shortcut or reference file	Local Google Drive synchronization reference; not a standalone spreadsheet workbook.

Understanding the Most Popular Spreadsheet Formats

1. XLS Format

The XLS format is a traditional Microsoft Excel workbook format associated with older Excel releases.

Excel 97, Excel 2000, Excel 2002 and Excel 2003 used this binary workbook format.

Although modern Excel versions can still open and save many XLS workbooks, the format has limitations compared with XLSX, including older worksheet size limits and differences in supported features.

2. XLSX Format

XLSX is the modern default workbook format introduced with Microsoft Office 2007.

It is based on Office Open XML, an XML-based document format packaged in a ZIP-based container.

An XLSX workbook can contain:

• Multiple worksheets.
• Cell values and formulas.
• Formatting and styles.
• Charts and images.
• Tables and named ranges.
• Workbook settings and metadata.

Unlike XLSM, the standard XLSX format cannot store VBA macro code.

3. XLSM Format

XLSM is an Excel macro-enabled workbook format. It uses the same general Office Open XML packaging approach as XLSX but supports embedded VBA macro code.

It is commonly used for automated reports, business applications and repetitive spreadsheet operations.

Because macros can execute code, users should only enable them in files from trusted sources.

4. XLSB Format

XLSB is the Excel Binary Workbook format.

Unlike XLSX, which uses XML-based workbook structures, XLSB stores workbook information using a binary format.

It can be useful for certain large or complex workbooks and supports advanced Excel features, including VBA projects.

However, it is less suitable for applications that need to directly inspect or manipulate workbook contents without using Excel-compatible tools.

5. ODS Format

ODS stands for OpenDocument Spreadsheet. It is an open standard spreadsheet format associated with the OpenDocument Format (ODF) family.

It is commonly used by LibreOffice Calc and Apache OpenOffice Calc and is supported by several other spreadsheet applications.

ODS is useful when users want to exchange spreadsheet documents without relying exclusively on Microsoft's proprietary legacy workbook formats.

However, converting complex spreadsheets between ODS and XLSX may result in differences in formatting, formulas, macros or other advanced features.

6. CSV Format

CSV stands for Comma-Separated Values. It is a text-based format used to exchange tabular information between different applications.

For example, a CSV file may contain:

Employee ID,Employee Name,Department,Salary
101,Rahul,Accounts,35000
102,Simran,Sales,42000
103,Amit,IT,50000

CSV is widely supported by spreadsheet software, databases, accounting applications and business systems.

However, CSV does not preserve typical spreadsheet features such as multiple worksheets, cell formatting, charts, formulas as working formulas or embedded VBA macros.

It is primarily suitable for transferring structured tabular data rather than complete spreadsheet workbooks.

7. TSV Format

TSV stands for Tab-Separated Values. It is similar to CSV, but individual fields are separated by tab characters instead of commas.

It is useful when the data itself contains commas or when transferring tabular information between applications that support tab-delimited text.

Difference Between XLS, XLSX, XLSM, XLSB, ODS and CSV

Feature	XLS	XLSX	XLSM	XLSB	ODS	CSV
Format type	Binary	XML-based package	XML-based package	Binary	OpenDocument package	Plain text
Multiple worksheets	Yes	Yes	Yes	Yes	Yes	No
Cell formatting	Yes	Yes	Yes	Yes	Yes	No
Formulas	Yes	Yes	Yes	Yes	Yes	No native formula support
VBA macros	Supported in applicable Excel versions	No	Yes	Yes	No native VBA support	No
Charts	Yes	Yes	Yes	Yes	Yes	No
Typical purpose	Legacy workbooks	Modern workbooks	Macro-enabled workbooks	Binary workbooks	Open-standard workbooks	Data exchange

Important: File compatibility depends on the application and its version. Even when two programs can open the same format, advanced formulas, macros, formatting and other workbook features may not transfer perfectly.
