How to format json

  1. Upload a .json file.
  2. Choose PRETTY and start the conversion.
  3. Download the PRETTY result.

Example

Upload api-response.json and download api-response.json.

When to use this conversion

  • Read a compact API response more easily.
  • Review nested objects and arrays during debugging.
  • Share readable JSON with a teammate.

Best practices

  • The file must contain valid JSON; comments and trailing commas are not accepted.
  • Formatting changes whitespace only; it does not repair invalid data.
  • Keep a copy of the original file before replacing it in a project.
