How It Works
Formatting
Simply paste your raw or minified JSON into the input box and click "Format JSON". The tool will parse and prettify your data with standard 2-space indentation.
Validation
Our tool automatically validates the JSON syntax. If there's an error, it will show you exactly what went wrong and where. Valid JSON will be confirmed with a success message.
