CSV Delimiter Converter

Convert a CSV between comma, semicolon, tab, and pipe delimited formats.

Switch the delimiter of a CSV without breaking quoted fields. Pick the input delimiter, pick the output delimiter, and download the re-encoded file. Quoting is reapplied so values containing the new delimiter, quotes, or line breaks stay intact.

How it works

  1. Paste your CSV into the editor and pick the input delimiter.
  2. Pick the output delimiter on the Change delimiter tab.
  3. Unlock the result and download the re-encoded file.

Use cases

  • Convert a European semicolon CSV to a standard comma CSV for an API.
  • Switch a comma CSV to semicolons so it opens cleanly in localised Excel.
  • Turn a pipe-delimited file into a CSV for a spreadsheet.
  • Re-encode a CSV with a custom delimiter for a niche import tool.

Frequently asked questions

Are quoted fields handled correctly?

Yes. The strict parser understands the input quoting and the writer reapplies quoting in the new delimiter, so a value containing the new delimiter is wrapped in quotes automatically.

Can I convert to TSV?

Yes. Pick Tab as the output delimiter and the download is a .tsv file with the correct content type.

Can I use a custom delimiter?

Yes, both sides accept a single custom character. Useful for niche formats that use ~, ^, or similar separators.

Will it touch my data?

No. This mode only re-encodes the delimiter and quoting. Cells, header, and row order are preserved exactly.

How long is the result kept?

The re-encoded file is auto-deleted after 7 days. Re-download is available during that window via the secure link.
