How to use the JSON Formatter
Paste the JSON and press Format. If something is wrong you get the exact error message, which usually points straight at the missing comma or bracket.
Frequently asked questions
Does it validate as well as format?
Yes — invalid JSON is reported with the parser's own error message.
Can I minify instead?
Yes, the Minify button removes all spacing for a compact single line.
Is my data sent to a server?
Never. Parsing happens entirely in your browser.
