Information about XLS and ODT file formats

Full name XLS - Microsoft Excel Binary File Format ODT - OpenDocument Text
File extension .xls .odt, .fodt
MIME type application/vnd.ms-excel application/vnd.-oasis.-opendocument.-text
Developed by Microsoft OASIS
Type of format Spreadsheet Document
Description 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". The Open Document Format for Office Applications (ODF), also known as OpenDocument, is an XML-based file format for spreadsheets, charts, presentations, and word processing documents. It was developed to provide an open, XML-based file format specification for office applications.
Technical details OpenOffice.org has created documentation of the Excel format. Since then, Microsoft has made the Excel binary format specification available to download freely. The original OpenDocument format consists of an XML document that has <document> as its root element. OpenDocument files can also take a ZIP compressed archive format containing many files and directories; these can contain binary content and benefit from ZIP's lossless compression to reduce file size.
