JSON to CSV
Paste a JSON array (or an API response with one inside) and download a CSV that opens in Excel or Google Sheets. Nested objects are flattened into columns like address.city.
Good to know
- If the JSON wraps its rows (like {"data": [...]}), that array is found automatically.
- Values with commas, quotes or line breaks are quoted correctly, so Excel won't split them.
- Excel in many European locales expects semicolons. Pick Semicolon if every row lands in one column.
- Everything happens in your browser. Your data isn't uploaded or stored.
