What this tool checks
The parser checks whether your JSON is valid and shows the browser error message if it is not. It is useful for API responses, app configuration, structured data drafts and debugging.
JSON Formatter
Paste JSON to validate it, beautify it with indentation, or minify it for production use.
Beautify or minify
Formatted JSON is easier to read and review. Minified JSON removes whitespace when you need a compact version for storage or transfer.
