Spreadsheet is a computer application that simulates a paper worksheet. It displays multiple cells that together formulate a grid consisting of rows and columns, each cell containing either alphanumeric text or numeric values. A spreadsheet cell may alternatively contain a formula that defines how the contents of that cell are to be calculated from the contents of any other cell (or combination of cells) each time any cell is updated.
Spreadsheets are frequently used for financial information as they robotically enable the re-calculation of the total sheet, after a modification to
a single cell is made. VisiCalc was typically considered the original electronic spreadsheet (although this has been challenged) and it helped turn the Apple II computer into a success and greatly assisted in their widespread application. Lotus 1-2-3 was the most popular spreadsheet in use when DOS was the dominant operating system. Excel is now considered to have the largest market share on the Windows and Macintosh platforms
MICROSOFT EXCEL
Microsoft had been developing Excel on the Macintosh platform for several years, eventually converting it into a powerful system. A port of Excel to Windows 2.0 resulted in a fully functional Windows spreadsheet. The highly robust Windows 3.x platforms of the early 1990s made it possible for Excel to take a significant amount of market share from Lotus. By the time Lotus responded with serviceable Windows products, Microsoft had started compiling their Office suite. Starting in the mid 1990s and continuing through to the present, Microsoft Excel has dominated the commercial electronic spreadsheet market.
