The same XLSX workspace powers the browser and desktop app. Formula calculation is partially supported; unsupported formulas and unsafe changes report diagnostics. The browser tools work now without installing an app.

Frequently asked questions

Do I need an account to use the browser tools?

No. The browser editor, converters and templates are available without an account.

Can I open the same file in the editor after converting it?

Yes. Choose Edit source from the converter to work with the same original workbook. Save XLSX when you want a copy with supported edits.

Is my workbook uploaded to a server?

The anonymous browser file tools process workbook contents locally. The website still makes ordinary requests for pages and sample files. Read the privacy page for details.

Which Excel files can I open?

Choose XLSX files with a combined size of 128 MiB or less. Legacy XLS files and password-protected or encrypted workbooks are not supported.
