How to Use Convert CSV Quote Character Online
- Paste your CSV. Any RFC-4180 compliant text works. Doubled-quote escapes (
"She said ""hi""") are parsed correctly and translated to the target quote character. - Set the delimiter. Comma, tab, semicolon, pipe, or a custom single character. Must differ from whichever quote character you choose - the tool refuses the conversion otherwise.
- Pick the source quote. Double, single, backtick, or any custom character. This is the character the parser will treat as the quoting boundary.
- Pick the target quote. Same options, plus a special None option that strips quotes wherever the field does not contain structural characters. When it does, a warning appears.
- Toggle quoting options. "Preserve quotes on fields that were quoted in the source" (on by default) keeps quoting exactly where it was. "Force-quote every field" wraps every cell - useful for strict importers.
- Click Convert or press Ctrl/Cmd+Enter. The input is also debounced to 250ms so typing updates the preview live.
- Copy or download. Copy places the converted CSV on the clipboard. Download picks

Frequently Asked Questions
What are CSV quote characters?
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.
Why would I need to change CSV quote characters?
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.
Does the tool handle escaped quotes correctly?
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"'.
What happens to fields that don’t contain quotes?
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.
Can I remove all quotes from a CSV?
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.
Is my CSV data uploaded to a server?
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.
How large of a CSV file can I process?
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.
Is this tool free to use?
Yes, completely free with no registration, no file limits, and no subscription fees.
Will changing quotes break my CSV structure?
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.
Can I use custom quote characters?
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.
