Questions

How do I convert XLSX to ODS?

Drop your XLSX file on this page, or choose it. Anyfile converts it on your device in a moment and the ODS downloads straight away. To change it first, open it in the spreadsheet editor.

Is my XLSX file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Can I convert several XLSX files at once?

Yes. Drop them together and you get one ZIP with every ODS inside.
