JSON Formatter & Validator

JSON (JavaScript Object Notation) is a lightweight data format used to exchange data between a server and a client. It is human-readable and easy to parse.

Paste your JSON into the editor — the tool will instantly validate it and highlight any syntax errors with line numbers and descriptions.

Formatting (beautifying) adds indentation and newlines to make JSON readable. Minifying removes all whitespace to make the JSON as compact as possible for transmission.
