File extensions used for various spreadsheets and workbook formats.

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 (.xls, .xlsx) now has the largest market share on the Windows and MacOS platforms, but you can find many other spreadsheet programs, often as part of some office productivity bundles, for example IBM Lotus 1-2-3 (.123), Numbers (.numbers), OpenOffice.org Calc, LibreOffice Calc (.ods), Gnumeric, Quatro Pro (.qpw) and more.

This category of file extensions is made up by files that are generally the proprietary output format of certain programs, or generally accepted standards and exchange formats supported in almost every modern spreadsheet editor.
