About the json formatter
JSON (JavaScript Object Notation) is the format most web APIs use to send data. A formatter re-indents compact or minified JSON so it is readable, and a minifier strips whitespace to shrink it for transport.
This tool also validates: if the JSON is malformed it reports the exact parser error so you can find the missing comma or bracket quickly.
Parsing happens entirely in your browser using the built-in JSON engine, so sensitive payloads are never uploaded anywhere.
