What is JSON?

JSON (JavaScript Object Notation) is a lightweight data format used for APIs, configuration files, and data storage. Easy for both humans and machines to work with.

Why Format & Validate?

Formatting makes JSON readable for debugging. Validation catches syntax errors before they cause problems. Minifying reduces file size for production.
