Microsoft Excel is a spreadsheet program written and distributed by Microsoft for computers using the Microsoft Windows operating system and Apple Macintosh computers. It is overwhelmingly the dominant spreadsheet application available for these platforms and has been so since version 5 1993 and its bundling as part of Microsoft Office.
Microsoft originally marketed a spreadsheet program called Multiplan in 1982, but it lost popularity to Lotus 1-2-3. This promoted development of a new spreadsheet called Excel which started with the intention to, in the words of Doug Klunder, 'do everything 1-2-3 does and do it better' . The first version of Excel was released for the Mac in 1985 and the first Windows version (dubbed version 2.0) was released in 1987. By 1988 Excel had started to oversell Lotus 1-2-3 and helped Microsoft achieve the position of leading PC software developer. This accomplishment, dethroning the king of the software world, solidified Microsoft as a valid competitor and showed its future of developing graphical software. The current version is 11, also called Microsoft Office Excel 2003.
Excel was the first spreadsheet that allowed the user to define the appearance of spreadsheets (fonts, character attributes and cell appearance). It also introduced intelligent cell recomputation, where only cells dependent on the cell being modified are updated, while previously spreadsheets recomputed everything all the time or waited for a specific user command.
When first bundled into Microsoft Office in 1993, Microsoft Word and Microsoft PowerPoint had their GUIs redesigned for consistency with Excel, still the killer app on the PC at the time.
Early in its life Excel became the target of a copyright lawsuit by another company already selling a software package named "Excel." As the result of the dispute Microsoft was required to refer to the program as "Microsoft Excel" in all of its formal press releases and legal documents. However, over time this practice has slipped.
Excel has extensive graphing capabilities, added support for Visual Basic for Applications as a scripting language in 1993 - aiming to add automation functionality, but making it a prime target for macro viruses. Excel offers a large number of user interface tweaks, however the essence of UI remains the same as in the original spreadsheet, VisiCalc: the cells are organized in rows and columns, and contain data or formulas with relative or absolute references to other cells.
Excel versions from 5.0 to 9.0 contain various Easter eggs.
Versions for the Apple Macintosh include:
Versions for Microsoft DOS include:
Versions for Microsoft Windows include:
