Convert Numbers to CSV
Turn an Apple Numbers (.numbers) file into a plain CSV file any other tool can import.

- Click Convert to download as a CSV file.
What this tool does to your file
An Apple Numbers spreadsheet is written out as comma-separated values that any other tool can import — which matters more for this format than most, because .numbers is readable by very little outside Apple’s own software. One sheet becomes one CSV, since the format holds nothing more. Formulas are written as their last calculated result. Rows are padded to the width of the widest row so column positions stay consistent down the file, because CSV consumers index by position and a ragged file shifts values into the wrong column. Styling, merged cells and column widths are dropped — CSV carries values only. Browsers outside macOS do not recognise .numbers and report it as a generic zip or as nothing, so the upload declares the type on your behalf.
What happens to your files
- No account needed — Every tool works as a guest. Signing in raises the limits and keeps your files together, but nothing asks you to register before you get a result.
- It runs in your browser — There is nothing to install and nothing to keep up to date. Files travel to our servers over an encrypted connection, and come back the same way.
- Your files stay yours — Files and results stay in your account until you delete them. Files from a guest session that is never linked to an account are removed automatically after a period of inactivity.
- Size limits, stated up front — Up to 10 MB per file as a guest, and up to 25 MB signed in. You see the limit before you upload, not after.
