Questions

How do I convert XLS to ODS?

Drop your XLS 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 XLS 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 XLS files at once?

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