About this tool
Everything JSON Pretty Print does happens on your own device. JSON Pretty Print validates and reshapes your JSON locally with no server round-trip.
Because parsing is local, sensitive payloads never leave the page. It behaves the same on desktop and mobile, with nothing stored remotely.
