JSON <-> CSV Converter
Paste JSON or CSV. The tool auto-detects the input and converts to the other format. Everything runs locally in your browser.
- Convert JSON arrays to CSV and CSV back to JSON.
- Choose delimiter, flatten nested fields, and preview output.
- Ideal for reports and spreadsheets.
Tip: For best CSV output, use a JSON array of objects (e.g. [{"id":1,"name":"A"}]). Nested objects can be
flattened (optional).
