About JSON to CSV

Convert JSON arrays to CSV with nested object flattening, delimiter options, table preview, and multi-format export — all in your browser.

How to use JSON to CSV

  1. 1Paste a JSON array of objects into the input area (or import a .json file).
  2. 2Click 'Prettify' to format the JSON for readability.
  3. 3Select the CSV delimiter (comma, semicolon, tab) and toggle headers.
  4. 4Preview the output in the table view to verify columns and data.
  5. 5Copy the CSV output or use it directly.

Tips

  • Nested objects are automatically flattened with dot notation (e.g., address.city) for complete data extraction.
  • Use semicolon as delimiter if your data contains commas in field values.
  • Check the row and column counts to verify all data was converted correctly.
