Frequently asked questions
Can Microsoft Excel open ODS files?
Yes — Excel 2007 and later can open and save ODS files natively. The conversion is generally good for standard spreadsheets, but complex formulas, macros (LibreOffice Basic vs VBA), and some formatting may not translate perfectly.
Does Google Sheets support ODS?
Yes — Google Sheets can import ODS files and export to ODS format (File → Download → ODS). The conversion handles most spreadsheet content well. Google Sheets treats ODS as a first-class format alongside XLSX.
