Description OpenOffice Spreadsheet is the default file type for the OpenOffice application called Calc. OpenOffice is a free suite of productivity tools which has been hailed as viable alternative to Microsoft Office. By allowing users to open and even save in Excel format, OpenOffice Calc is often used to overcome incompatibility issues.

Technical Details The OpenOffice Spreadsheet file format was developed by the OASIS industry consortium. Files are saved and compressed using ZIP compression which generally makes the file size smaller than the equivalent file created by Microsoft Excel and saved as a XLS file. Usually the file will consist of an XML file, directories and thumbnails. By utilising an open source compression technique, it is often possible to repair partially corrupted files. It is also possible for advanced users to edit the rate of compression, therefore achieving higher compression ratios.

Description Microsoft Excel is a commercial spreadsheet application written and distributed by Microsoft for Microsoft Windows and Mac OS X. Pre-2007 versions of Excel use XLS as the primary format for saving files. It features calculation, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications. It has been a very widely applied spreadsheet for these platforms, especially since version 5 in 1993, and it has almost completely replaced Lotus 1-2-3 as the industry standard for spreadsheets. Excel forms part of Microsoft Office. The current versions are 2010 for Microsoft Windows and 2011 for Mac OS X.
