About this tool
A JSON formatter takes raw or minified JSON data and reformats it with proper indentation and line breaks to make it human-readable.
Yes, the formatter validates your JSON and highlights errors if the syntax is invalid. You can also use the Repair JSON button to automatically fix common issues.
Minified JSON removes all whitespace to reduce file size, while formatted JSON adds indentation and line breaks to improve readability.
No, all formatting is done locally in your browser. Your data never leaves your device.
