About this tool

Pure client-side JSON parsing using JSON.parse. noeval, noFunction constructor. Diff is recursive path-based, not line-based (works for reordered keys). No data leaves your browser.

Why this exists

Every team that touches an API needs a JSON tool. The popular ones (jsonformatter.org, jsondiff.com) work but look terrible and run ads. This is the same UX, no ads, no tracking, accessible.

The Anamata Records waiata metadata in the sample is a realistic example. waiata metadata + iwi consent + Local Contexts labels. Useful for previewing how a release's public JSON would look.
