📝 JSON Input
Why format JSON?

JSON is the default data format for APIs, configuration files, and frontend-backend communication. Formatting it correctly makes debugging easier, improves readability, and helps you spot missing commas, quotes, or braces quickly.

Typical situations:

  • testing API responses in Postman or browser dev tools
  • cleaning up minified payloads from services
  • validating configuration objects before deployment
