Basic information about spreadsheets and how to open workbook files
About spreadsheets and workbooks
A spreadsheet is a computer application or program, which simulates a paper, or accounting worksheet. It displays multiple cells that together make up a grid consisting of rows and columns, with each cell containing alphanumeric text, numeric values or formulas. A formula defines how the content of that cell is 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 statistical or financial information because of their ability to re-calculate the entire sheet automatically after a change to a single cell is made.
Visicalc is usually considered the first spreadsheet program, and it helped turn the Apple II computer into a success and greatly assisted in their widespread application. Lotus 1-2-3 was the leading spreadsheet when MS-DOS was the dominant operating system on the market. Microsoft Excel now has the largest market share on the Windows and Macintosh platforms but many other spreadsheet applications are being used or were developed in the past. Other popular spreadsheet programs include IBM Lotus 1-2-3, Apple Numbers, OpenOffice.org Calc, Gnumeric, Quatro Pro and other.
