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.

Technical Details XLSX improves file and data management and data recovery. XLSX extends what is possible with the binary files of earlier versions. Any application that supports XML can access and work with data in the new file format. The application does not need to be a Microsoft product it can be any application. Users can also use standard transformations to extract or repurpose the data. In addition, security concerns are drastically reduced because the information is stored in XML, which is essentially plain text. Thus, the data can pass through corporate firewalls without hindrance.
