What is JSON Formatter?
JSON (JavaScript Object Notation) is a lightweight data format used for data exchange between servers and web applications. A JSON formatter takes raw or minified JSON and adds proper indentation and line breaks, making it easy to read and debug. Our tool also validates your JSON and shows exactly where errors occur.

- Validate JSON and highlight errors with line numbers
- Minify / compress JSON to reduce size
