What does a JSON formatter do?

A JSON formatter turns cluttered or minified JSON into a cleanly indented, readable structure while checking that the syntax is valid. It can also minify JSON again.

What does "validate JSON" mean?

Validation checks whether the JSON is syntactically correct – that all brackets, quotes and commas are right. Errors are shown with their position so you can find them quickly.

Is my data sent anywhere?

No. Formatting and validation happen entirely in your browser. Your JSON is not sent to the server or stored.

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data interchange format that is easy to read for both humans and machines. It is widely used for APIs, configuration files and data exchange between web services. This tool lets you format JSON data (pretty print), minify it or validate it for syntax errors.
