How do I convert a Numbers file to CSV?

Upload the .numbers file, press Convert, and download the .csv. Open it in any spreadsheet, text editor, or import it into your database or CRM.

Which sheet is exported?

The first sheet in the document. CSV is a single-table format, so it cannot hold several sheets. If you need a different sheet, drag it to the front in Numbers and save, or convert to Excel to keep everything.

What if the sheet contains several tables?

All tables on that sheet are written to the CSV one after another, in the order they appear, separated by blank rows. For the cleanest result, keep one table per sheet before converting.

What happens to formulas?

CSV has no formulas, so each formula cell is replaced by its last calculated value — exactly what you would see on screen in Numbers.

Which delimiter and encoding are used?

Comma-separated, UTF-8 encoded, with double quotes around any value that contains a comma, quote or line break. That is what Excel, Google Sheets, Python, R and every database import expect.

Will numbers and dates keep their formatting?

Values are exported as displayed, so currency symbols, thousands separators and date formats appear as text. If your import tool needs raw values, switch the cells to a plain number format in Numbers before converting.

My Numbers file is a folder — how do I upload it?

Compress it in Finder (right-click → Compress) and upload the resulting .zip. The converter recognises the bundle inside.

Is there a file size limit?

25 MB per upload and 60 seconds per conversion. That comfortably covers spreadsheets with hundreds of thousands of cells.

No. Processing happens in a temporary workspace on our server and the temporary file is deleted immediately after the CSV has been delivered.

Yes — free, no signup, no limits beyond the fair-use rate limit shared by all converters.

Good to know

CSV is the lowest common denominator of data exchange, and that is precisely its strength. Every database, analytics tool, CRM import wizard, programming language and spreadsheet reads it. When a colleague sends a Numbers file and you need the figures in something else — Postgres, a Python notebook, Mailchimp, Google Sheets — turning it into CSV removes every question about compatibility. There is nothing to install and nothing that can render differently.

The trade-off is that CSV holds data and nothing else: no formulas, no formatting, no second sheet, no charts. This converter therefore exports the first sheet and writes values as they are displayed. Two habits make the output cleaner. First, keep a single table per sheet, with a header row and no merged cells, so the CSV is a plain rectangle. Second, set number and date cells to a plain format in Numbers (no currency symbol, ISO-style dates) if the destination will do arithmetic on them — display formatting travels into the text otherwise.

Once you have the file, the browser-side CSV tools take over without any further upload: preview it, trim whitespace and fix line endings, switch to semicolons for European Excel, or turn it into JSON for an API. If you need the whole workbook with all its sheets, use Numbers to Excel instead.
