How does it work?
Parsing uses the browser's native JSON.parse, so it's strict and fast. Pretty-printing and minification go through JSON.stringify with your chosen indent. Nothing is sent to a server, no logs, no analytics on your payload.
Why sort keys?
Sorting keys alphabetically produces a deterministic output — useful for generating stable diffs in version control, comparing two payloads byte-for-byte, or building a content hash that doesn't change just because a serializer reordered fields.
