Convert CSV Quote Character

Characters that mark the beginning and end of a field that contains special content – the delimiter, a newline, or the quote itself. Double quote is the RFC-4180 standard; single quote and backtick appear in alternative formats.

Importing into a tool that expects a different convention, matching a legacy or region-specific format (some European Excel profiles use single quotes), or preparing output for a system that already uses " as a literal character in data.

Yes. Doubled quotes inside a quoted field are parsed as one literal quote character. When the output uses a different quote, doubling is re-applied with the new character – so "She said ""hi""" going double → single becomes 'She said "hi"'.

With “Preserve quotes on fields that were quoted in the source” on (default), unquoted fields stay unquoted. With “Force-quote every field” on, every cell is wrapped in the new quote.

Yes – pick None as the target quote. Fields that are safe to unquote (no delimiter, no newline, no quote char) come out bare. Fields that would break the structure trigger a yellow warning so you can review.

No. All parsing and re-serialisation runs in your browser with plain JavaScript. The tool never issues a network request for your data – no upload, no telemetry.

About 50,000 rows convert in under 100ms on a modern laptop. Bigger files work but the 250ms live-preview debounce is your friend – paste the full blob and the tool re-parses once per idle burst.

Yes, completely free with no registration, no file limits, and no subscription fees.

No. The tool parses with a real RFC-4180 state machine and re-emits with escape-by-doubling in the new quote character. Structure, field count, and cell contents are preserved exactly.

Yes. Pick “Custom…” in either the source or target dropdown and type a single character. The tool enforces that the quote and delimiter differ, because no downstream CSV parser handles that ambiguity.
