JSON to CSV & CSV to JSON Converter
Convert between JSON and CSV in one click. For developers and data analysts. Pure JavaScript, no upload—handles thousands of rows in the browser.
How it works
JSON is used in APIs and configs; CSV is used in spreadsheets and data exchange. This tool converts either way: paste JSON (array of objects) to get CSV with headers, or paste CSV to get JSON.
Conversion runs in your browser with no external libraries. Paste your data, click the direction you need, and copy or use the result. Handles large datasets quickly.
Essential for developers, analysts, and marketers who move data between systems. Your data never leaves your device.
