What is JSON formatting?

JSON formatting (also called pretty-printing) adds indentation and line breaks to make JSON code more readable for humans while keeping it valid.

Can this tool validate my JSON?

Yes! The tool automatically validates JSON as you type and shows detailed error messages if the JSON is invalid.
