About converting JSON to CSV
Converting JSON to CSV is a common step when moving data between spreadsheets, APIs and apps. This converter handles the details correctly — CSV fields wrapped in quotes can contain commas, line breaks and escaped quotes, and you can choose a comma, semicolon or tab delimiter.
The whole conversion runs in your browser, so even large or sensitive datasets never touch a server. Need to go the other way? Use the Swap button or the main CSV ⇄ JSON converter, which does both directions.
Frequently asked questions
Is my data uploaded?
No — the JSON-to-CSV conversion happens entirely in your browser, so your data stays on your device.
Does it handle quotes and commas in fields?
Yes. CSV is read and written following RFC 4180, so quoted fields can safely contain commas, newlines and escaped quotes in either direction.
Can I change the delimiter?
Yes — choose comma, semicolon or tab, which covers standard CSV, European exports and TSV files.
Can I convert the other direction?
Yes. Hit Swap, or use the main converter, to go from CSV back to JSON.
