Frequently Asked Questions

What does JSON formatting do?: JSON formatting (or prettifying) adds proper indentation, line breaks, and spacing to JSON data, making it easier to read and understand.
How do I validate JSON?: Our JSON formatter automatically validates JSON syntax and shows error messages if the JSON is invalid, including the line number where the error occurs.
Can I minify JSON?: Yes, our tool can both format (prettify) and minify JSON. Minifying removes all unnecessary whitespace to reduce file size.
What's the difference between JSON and JavaScript objects?: JSON is a text format based on JavaScript object syntax, but JSON keys must be strings (in quotes) and doesn't support functions or comments.
