Paste raw or minified JSON into the input box and click Format to beautify it with proper indentation. Click Minify to strip all whitespace for compact output. Invalid JSON shows an error message with the exact issue.
Frequently Asked Questions
Does this validate my JSON?
Yes. If your JSON is invalid, an error message shows exactly what's wrong. Valid JSON formats and displays cleanly.
Is my JSON data safe?
All processing runs in your browser via JavaScript. Your JSON is never sent to any server.
