The .xls file format
Microsoft Excel is a spreadsheet package created by Microsoft and is used in Windows, Mac OS X, Android and iOS. MS Excel has capabilities such as calculation, drawing graphs and pivot tables, and programming through Visual Basic for Applications. It has taken over from Lotus 1-2-3 as the accepted standard for spreadsheets. The XLS extension in use until 2007 has now been replaced by an Open Office XML file format denoted by XML or XMLSS. Excel 2007 is backwards compatible meaning it can read DOS-based file formats.
