| WHAT IS MICROSOFT EXCEL? | |
| Microsoft Excel is a spreadsheet program written and distributed by Microsoft for computers using the Microsoft Windows operating system and for Apple Macintosh computers. It features an intuitive interface and capable calculation and graphing tools which, along with aggressive marketing, have made Excel one of the most popular microcomputer applications to date. It is overwhelmingly the dominant spreadsheet application available for these platforms and has been so since version 5 in 1993 and its bundling as part of Microsoft Office.

| MICROSOFT EXCEL HISTORY | |
|
Microsoft originally marketed a spreadsheet program called Multiplan in 1982. It soon lost popularity to Lotus 1-2-3. This promoted development of a new spreadsheet called Excel which started with the intention to do everything 1-2-3 does and do it better . The first version was released for the Mac in 1985 and the first Windows version was released in November 1987. Lotus was slow to bring 1-2-3 to Windows and by 1988 Excel had started to outsell 1-2-3 and helped Microsoft achieve the position of leading PC software developer. This accomplishment solidified Microsoft as a valid competitor and showed its future of developing graphical software. Microsoft pushed its advantage with regular new releases, every two years or so.
Early in its life Excel became the target of a trademark 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. Excel offers a large number of user interface tweaks. The cells are organized in rows and columns, and contain data or formulas with relative or absolute references to other cells. 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 re-computation, 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. Excel has extensive graphing capabilities. Since 1993, Excel includes Visual Basic for Applications (VBA), a programming language based on Visual Basic which adds the ability to automate tasks in Excel and to provide user defined functions (UDF) for use in worksheets. The automation functionality which VBA provides has exposed Excel as a target for macro viruses. | |
