Information about WKS and XLS file formats

Full name Microsoft Works Spreadsheet XLS - Microsoft Excel Binary File Format
File extension .wks .xls
MIME type application/vnd.ms-works, application/x-msworks, application/vnd.ms-excel application/vnd.ms-excel
Developed by Microsoft Microsoft
Type of format Document File Spreadsheet
Description The .wks file extension relates to spreadsheets created by the Microsoft Works suite. Microsoft Works provided a less expensive and more simplistic spreadsheet program than Microsoft Excel. Often bundled with new PCs, the suite of products was discontinued in 2008. The file type was particularly unpopular due to a lack of compatibility with other programs, including Microsoft Excel. Microsoft Excel, up until 2007 version used a proprietary binary file format called Excel Binary File Format (.XLS) as its primary format. Excel 2007 uses Office Open XML as its primary file format, an XML-based format that followed after a previous XML-based format called "XML Spreadsheet".
Technical details A .wks file allows rows and columns to be defined in a file within Microsoft Works. Other features commonly found in other spreadsheet applications are also in .wks files, including formulas, charts, and graphs. Although Excel 2003 supports .wks files, Excel 2007 does not support them. OpenOffice.org has created documentation of the Excel format. Since then, Microsoft has made the Excel binary format specification available to download freely.
