A spreadsheet is used for organizing, analyzing, manipulating, and visualizing data. It consists of a table with rows and columns. The table cells may contain manually entered data or the results computed from the data of other cells.

NOTE: XLS files are saved in the Excel Binary File Format, which was the primary format until the Office Open XML format was introduced with Excel 2007. Most Excel files are now saved in the Office Open XML format, with an .XLSX file extension. However, Microsoft Excel an many other spreadsheet programs still support the older XLS format.
