How to use

Paste JSON — the line below shows whether it is valid, with the error position if not.
"Beautify" formats with the chosen indent; "Minify" strips all whitespace.
"Sort keys" recursively orders object keys — handy for diffing.

Input is processed only in your browser and is never sent anywhere.

Trailing commas or comments?: This uses the standard JSON.parse, so trailing commas, comments and single quotes are invalid.
