Input
Parsed with the source delimiter, re-emitted with the target.
Result
No input yet.
Paste CSV and choose two different delimiters.
CSV Delimiter Converter re-emits the same rows under a different separator - comma, semicolon, tab or pipe - after parsing the text with the source delimiter you name. Parsing first is what makes the switch safe: a field containing a comma inside quotes would be torn apart by a find-and-replace, and the page instead reads the structure and writes it back with the quoting the target requires. Choosing the same delimiter on both sides is rejected rather than returning the input unchanged, because a conversion that does nothing is almost always a mis-set control. Every value stays text: nothing is interpreted as a number, a date or a formula, so a leading zero or a decimal comma comes out as it went in. It is the tool for adapting a comma export to a locale where Excel expects semicolons, for turning a report into tab-separated values that paste cleanly into a document, and for checking that quoted content survives a move before the file reaches an importer. The converted text is offered to copy or download at once, and the work happens in your browser, so the rows never leave the device.
How to use CSV Delimiter Converter

What you get
- The same rows re-emitted under the target delimiter, with fields that contain it re-quoted as needed.
- A rejection when source and target are the same, rather than an unchanged file that looks converted.
- Copy and download of the converted text, produced entirely in the browser.
When to use CSV Delimiter Converter
- Adapt comma CSVs for locales where Excel expects semicolons.
- Convert exports to tab-separated values for pasting into documents.

Frequently asked questions about CSV Delimiter Converter
Does CSV Delimiter Converter upload my data?
No. Parsing and conversion run locally in your browser; nothing is sent, stored, or logged.
What happens to quoted fields?
Fields containing the old delimiter stay quoted; re-quoting follows RFC 4180 under the new delimiter.
Why was my input rejected?
Either the source delimiter does not match the text, the delimiters are identical, or a quote is unbalanced.
Does safe output apply here too?
Yes. Formula-risky cells gain a leading quote unless you switch the guard off.
