CSV Delimiter Converter

Change a file's delimiter: read CSV with one separator and write it with another, such as comma to tab (TSV) or pipe. Runs in your browser.

What it does

This tool re-delimits your data: it parses the input with the delimiter you pick under "From" and writes it out with the "To" delimiter, re-quoting fields as needed.

Use it to make a TSV for a tool that expects tabs, a semicolon file for a European spreadsheet, or a pipe-delimited file when values contain commas.

Private and unlimited

Every conversion happens locally in your browser, so your data is never uploaded, logged or stored on a server. You can use it on confidential exports without a second thought, and it keeps working offline once the page has loaded.

There is no sign-up, no watermark and no row limit: the only ceiling is your device's memory.

Ofte stilte spørsmål

Will it re-quote fields correctly?

Yes. It fully parses the input then re-serialises it, so any field that contains the new delimiter, a quote or a line break is quoted according to the CSV standard.

Which delimiter should I use?

Comma is the standard. Pick semicolon in regions where the comma is the decimal separator (common in German and other European exports), tab for TSV files, or pipe when your values already contain commas.

Is there a row or file-size limit?

There is no fixed row cap or daily quota. Because everything runs locally the practical limit is your device's memory, which comfortably handles the tens of thousands of rows most exports contain.

Is my data uploaded anywhere?

No. The conversion runs entirely in your browser with client-side JavaScript, so nothing you paste or drop ever leaves your device. That makes it safe for spreadsheets that contain customer emails, financial figures or other sensitive data.
