JSON to CSV / CSV to JSON Converter

Convert structured JSON arrays into CSV rows or turn CSV data back into clean JSON.

About JSON and CSV Conversion

This converter helps developers move data between API-friendly JSON and spreadsheet-friendly CSV without leaving the browser. It is especially useful for importing exports, preparing reports, and testing integrations that expect a different format.

For JSON to CSV, paste an array of objects so each object becomes one row.
CSV input should include a header row for clean field names in JSON output.
Quoted CSV values are supported, so commas inside fields can still be converted safely.
