  2. Convert it to .ODS in a few seconds.
  3. Download your new .ODS file.

What to expect

  • VBA macros are not saved in .ods - macro code is silently dropped on conversion.
  • Excel PivotTables convert to LibreOffice DataPilot tables; complex groupings or calculated fields may not carry over fully.
  • Excel-only features such as Power Query, sparklines, and structured Table objects have no .ods equivalent and are dropped or flattened.

Frequently asked questions

Will my formulas still work after converting?
Standard formulas (SUM, IF, VLOOKUP, etc.) translate correctly. Very obscure Excel-only functions may show an error if no ODF equivalent exists.
Do I lose anything important when converting XLSX to ODS?
For most files, no. Practical losses are VBA macros, Power Query steps, and some Excel-specific chart types; plain data, standard formulas, and basic formatting survive intact.
Can LibreOffice open XLSX files directly?
Yes - LibreOffice Calc reads and edits .xlsx files directly; Save As .ods only when you need to change the format.
Can I convert ODS back to XLSX later?
Yes, the same apps support the reverse direction - open the .ods and choose File > Save As > .xlsx.
