How to Use

- Paste a JSON array of objects, or CSV text with a header row.
- The converted result appears automatically and can be copied.
How the Conversion Works
For JSON → CSV, the tool takes an array of flat objects (e.g. [{"name":"Alice","age":30}]) and uses the keys of the first object as CSV column headers. For CSV → JSON, the first row is treated as headers, and each following row becomes one JSON object with those headers as keys.
