Make API responses and configuration files readable again. Validate JSON as you format it, choose your indentation, or compress it for transport.

  2. Choose two spaces, four spaces, or minified output.
  3. Copy the result or download it as a .json file.
Your work stays yours.
Tool inputs are processed locally in your browser and are never sent to KitVerse servers. Clear the workspace when using a shared device.
Common questions
Can this repair invalid JSON?

It identifies parsing errors but does not silently rewrite invalid data. Fix the reported syntax and format again.

Are object keys sorted?

No. Formatting preserves the original key order.
