Multiplan is a spreadsheet program developed by Microsoft and introduced in 1982 as a competitor to VisiCalc.
Multiplan was released first for computers running CP/M; it was developed using a Microsoft proprietary p-code C compiler [1] as part of a portability strategy that facilitated ports to systems such as MS-DOS, Xenix, Commodore 64 and 128, TI-99/4A (on four 6K GROMs and a single 8K ROM), Radio Shack TRS-80 Model II, TRS-80 Model 4, TRS-80 Model 100 (on ROM), Apple II, AT&T UNIX PC, and Burroughs B20 series. The CP/M version also ran on the TRS-80 Model II and 4, Commodore 128, and Apple II with a CP/M card. In France, Multiplan was also released for the Thomson computers in 1986 and same year on Japan for MSX compatible computers with name MSX-Plan.
Despite the release of Microsoft Chart, a graphics companion program, Multiplan continued to be outsold by Lotus 1-2-3. Multiplan was replaced by Microsoft Excel, which followed some years later on both the Apple Macintosh (1985) and Microsoft Windows (1987).
Although over a million copies were sold, Multiplan was not able to mount an effective challenge to Lotus 1-2-3. According to Bill Gates, this was due to the excessive number of ports (there were approximately 100 different versions of Multiplan). He also believed that it was a mistake to release 8-bit versions instead of focusing on the newer 16-bit machines and as a result, "We decided to let [Lotus] have the character-based DOS market while we would instead focus on the next generation–graphical software on the Macintosh and Windows." [ citation needed ] Around 1983, during the development of the first release of Windows, Microsoft had plans to make a Windows version. However the plans changed a year later.
A version was available for the Apple Lisa 2 running Microsoft/SCO Xenix 3. It fit on one 400K microfloppy diskette. [3]
A fundamental difference between Multiplan and its competitors was Microsoft's decision to use R1C1 addressing instead of the A1 addressing introduced by VisiCalc. Although R1C1-style formulae are more straightforward than A1-style formulae [4] – for instance, "RC[-1]" (meaning "current row, previous column") is expressed as "A1" in cell B1, then "A2" in cell B2, etc. – most spreadsheet users prefer the A1 addressing style introduced by VisiCalc. [5] [6]
Microsoft carried Multiplan's R1C1 legacy forward into Microsoft Excel, which offers both addressing modes, although A1 is Excel's default addressing mode.
Ahoy! called the Commodore 64 version of Multiplan, distributed by Human Engineered Software, a "professional quality spreadsheet ... There is not enough room in this article to mention all the mathematical operations performed ... Documentation is lengthy but well written". [7] A second review in the magazine noted the limitation of the computer's 40-column screen, but praised the ability to stop any ongoing action. It also praised the documentation, and concluded that "its ease of use and foolproof design make Multiplan an outstanding value". [8] BYTE said that "Multiplan for the Macintosh is a winner", stating that combining other versions' power and features with the Macintosh's graphics and user interface "rivals, and in many ways exceeds, anything else available in the spreadsheet genre".

Daniel Singer Bricklin is an American businessman and engineer who is the co-creator, with Bob Frankston, of VisiCalc, the first spreadsheet program. He also founded Software Garden, Inc., of which he is currently president, and Trellix, which he left in 2004. He currently serves as the chief technology officer of Alpha Software.
Lotus 1-2-3 is a discontinued spreadsheet program from Lotus Software. It was the first killer application of the IBM PC, was hugely popular in the 1980s, and significantly contributed to the success of IBM PC-compatibles in the business market.
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS. It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA). Excel forms part of the Microsoft 365 suite of software.
A spreadsheet is a computer application for computation, organization, analysis and storage of data in tabular form. Spreadsheets were developed as computerized analogs of paper accounting worksheets. The program operates on data entered in cells of a table. Each cell may contain either numeric or text data, or the results of formulas that automatically calculate and display a value based on the contents of other cells. The term spreadsheet may also refer to one such electronic document.
VisiCalc is the first spreadsheet computer program for personal computers, originally released for the Apple II by VisiCorp on October 17, 1979. It is considered the killer application for the Apple II, turning the microcomputer from a hobby for computer enthusiasts into a serious business tool, and then prompting IBM to introduce the IBM PC two years later. More than 700,000 copies were sold in six years, and up to 1 million copies over its history.
Lotus Improv is a discontinued spreadsheet program from Lotus Development released in 1991 for the NeXTSTEP platform and then for Windows 3.1 in 1993. Development was put on hiatus in 1994 after slow sales on the Windows platform, and officially ended in April 1996 after Lotus was purchased by IBM.
Lotus Software was an American software company based in Massachusetts; it was sold to India's HCL Technologies in 2018.
Microsoft BASIC is the foundation software product of the Microsoft company and evolved into a line of BASIC interpreters and compiler(s) adapted for many different microcomputers. It first appeared in 1975 as Altair BASIC, which was the first version of BASIC published by Microsoft as well as the first high-level programming language available for the Altair 8800 microcomputer.
Visi On is a graphical user interface (GUI)-based operating environment program for IBM compatible personal computers running MS-DOS. Visi On was developed by VisiCorp. It was one of the first GUIs on a personal computer. Visi On was never popular, as it had steep minimum system requirements for its day, but it was influential in the development of later GUIs like Microsoft Windows.
VisiCorp was an early personal computer software publisher. Its most famous products were Microchess, Visi On and VisiCalc.
SuperCalc is a CP/M-80 spreadsheet application published by Sorcim in 1980.
Data Interchange Format (.dif) is a text file format used to import/export single spreadsheets between spreadsheet programs.
Dan Fylstra is a pioneer of the software products industry.
The TRS-80 Model II is a computer system launched by Tandy in October 1979, and targeted at the small-business market. It is not an upgrade of the original TRS-80 Model I, but a new system.
Sorcim Corporation was an early start-up company in Silicon Valley, founded in June 1980 by Richard Frank, Paul McQuesten, Martin Herbach, Anil Lakhwara, and Steve Jasik - all former Control Data Corporation employees working in the Language Group in Sunnyvale, CA. Jasik left company early on, to develop the MacNosy product for the Macintosh.
Home computers were a class of microcomputers that entered the market in 1977 and became common during the 1980s. They were marketed to consumers as affordable and accessible computers that, for the first time, were intended for the use of a single, non-technical user. These computers were a distinct market segment that typically cost much less than business, scientific, or engineering-oriented computers of the time, such as those running CP/M or the IBM PC, and were generally less powerful in terms of memory and expandability. However, a home computer often had better graphics and sound than contemporary business computers. Their most common uses were word processing, playing video games, and programming.
