JSON to CSV Converter
Convert JSON data to CSV format for spreadsheets and data export.
How It Works
Paste valid JSON in the input box—usually an array of objects, e.g. [{ "name": "Alice", "age": 30}, ...]. Click "Convert to CSV". The first object's keys become the CSV header; each object's values become a row. Commas and newlines inside values are escaped so the CSV is valid. You can copy the result or download it as a .csv file. Conversion runs in your browser; nothing is sent to a server.
Use this for API responses, export scripts, or any JSON data you need in spreadsheet form. No account required.
