How do I format JSON?

Paste your JSON into the input field and click "Format". The tool will add proper indentation and line breaks to make your JSON readable. You can customize the indentation level.

What is the difference between format and minify?

Formatting (beautifying) adds whitespace and indentation for readability. Minifying removes all unnecessary whitespace to reduce file size, ideal for production use.

Can I sort JSON keys alphabetically?

Yes! Enable the "Sort keys" option to alphabetically sort all object keys, including nested objects. This is useful for comparing JSON or maintaining consistent ordering.

How do I remove null values from JSON?

Enable the "Remove nulls" option before formatting. This will recursively remove all null values from objects and arrays in your JSON.
