Information about XLS and ODS file formats

🔸 File format XLS ODS
🔸 Full name XLS - Microsoft Excel Binary File Format ODS - OpenDocument Spreadsheet
🔸 File extension .xls .ods, .fods
🔸 MIME type application/vnd.ms-excel application/vnd.-oasis.-opendocument.-spreadsheet
🔸 Developed by Microsoft OASIS
🔸 Type of format Spreadsheet Spreadsheet
🔸 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.
