📝 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
