About the JSON to CSV Converter

JSON is expressive and flexible but isn't the easiest format for humans to browse, filter, or chart. Spreadsheet applications like Excel and Google Sheets are purpose-built for exactly those tasks. This converter takes a JSON array of objects and produces a CSV where the keys become column headers and each object becomes a row — ready to open directly in any spreadsheet tool.

When to use this tool

Use this converter when you've received a JSON export from an API, database, or application and want to analyse or visualise it in a spreadsheet without writing any code.

Tips for best results

  • The converter works best with a JSON array of flat objects — each object should have the same keys.
  • Nested objects within JSON are not fully flattened — deeply nested structures may require pre-processing.
  • Field values containing commas are automatically quoted in the CSV output to prevent parsing errors.

FAQs

A flat JSON array of objects works best — like [{"name":"Alice","age":30},{"name":"Bob","age":25}]. Each object becomes a row, and the keys become column headers.

The converter uses the keys from the first object as headers. Objects missing some keys will produce empty cells for those columns.

Nested objects will be partially represented, but deeply nested structures don't map cleanly to a flat spreadsheet. For complex JSON, you may need to flatten the structure first using a tool like jq.

Yes. The CSV output wraps field values that contain commas, quotes, or newlines in quotation marks, following CSV specification standards.

Yes. Download the CSV, then open it in Excel, Google Sheets, LibreOffice Calc, or any spreadsheet application. All standard spreadsheet software supports CSV import.
