What to know about NUMBERS to CSV conversion

CSV holds a single table: convert the active sheet only, or all sheets at once (as a ZIP with one file per sheet).
Cell values are exported as they were last calculated; formulas, formatting and charts are not part of the output.
The CSV file includes a UTF-8 byte order mark so Excel opens accented characters correctly.
CSV is best for importing data into databases, CRMs and apps, and opens in any spreadsheet, database or text editor.

Frequently asked questions

Is it safe to convert NUMBERS to CSV here?

Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.

Is there a file size limit?

There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.

Can I convert several NUMBERS files at once?

Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
