Format guide

ODS

OpenDocument Spreadsheet

ODS is the OpenDocument format spreadsheet, used by LibreOffice Calc, Apache OpenOffice Calc, and Collabora Online. ZIP-packaged XML structure standardized by ISO/IEC 26300. The free/open-source counterpart to Microsoft's XLSX. Excel reads ODS but with feature loss on complex formulas; LibreOffice reads XLSX with similar caveats.

How to open a ODS file

LibreOffice Calc (free, every desktop OS) is the native editor. Microsoft Excel opens ODS but pins it as 'OpenDocument' with a downgraded ribbon. Google Sheets imports ODS via File → Import.
