JSON formatting (beautifying) adds proper indentation and line breaks to make compact JSON human-readable. Minifying does the reverse — removes all whitespace to reduce file size.
How does the JSON validator work?
The tool uses JavaScript's built-in JSON.parse() to validate your JSON. If there's a syntax error, it shows the exact error message including the character position where parsing failed.
Is my JSON data safe?
Completely safe. All processing is done in your browser using JavaScript. No data is sent to any server.
Can I sort JSON keys alphabetically?
Yes! Use the "Sort Keys" option to sort all keys in the JSON object alphabetically in ascending (A→Z) or descending (Z→A) order.
