How to format and validate JSON

Minified JSON is hard to read and debug. Pretty-print it safely without sending data to a server.

Open the tool: JSON formatter

Steps

  1. Open the JSON formatter and paste your JSON.
  2. Click format to indent and validate syntax.
  3. Fix any highlighted errors line by line.
  4. Copy the cleaned JSON back to your project.

Tips

  • Validate API responses before committing config files.
  • Use the JSON editor when you need to edit tree nodes visually.
