About JSON / CSV Converter
JSON and CSV both hold tabular data but suit different tools — JSON for APIs and code, CSV for spreadsheets. This converts a flat JSON array of objects to CSV and back.
How to use it
- Paste a JSON array of objects, or CSV text.
- Pick the conversion direction.
- Review the output columns or keys.
- Copy the result.
Frequently asked questions
- What JSON shape does it expect?
- An array of objects with consistent keys. Deeply nested objects do not map cleanly to flat CSV columns.
- How are commas and quotes in values handled?
- Values containing commas, quotes, or newlines are wrapped in double quotes following the usual CSV rules.
- Is my data uploaded?
- No. Conversion runs in your browser.
