JSON Strict Prettifier (Sort Keys + Configurable Indent)

Standard JSON formatters output keys in insertion order. For diffing, version control, or reproducibility, you often want sorted keys — same data always produces the same string. This prettifier adds key sorting, configurable indent width / character, and optional pinned-first-key ordering for common fields like id and type.

How to use the JSON Strict Prettifier (Sort Keys + Configurable Indent)

Paste JSON. Configure indent width, optional key sorting, and any keys you want pinned to the top of every object (handy for putting id and type first). Output updates live.
