How do you handle JSON diffs when arrays get reordered?

One thing I kept running into while building JSON Semantic Diff is that comparing JSON arrays by index breaks down pretty quickly.

If the same objects appear in a different order, a small change can suddenly look like dozens of modifications.

I ended up treating it as an identity problem first: which object on the left corresponds to which object on the right? This semantic diff tool tries to infer that from the data, and falls back when it s ambiguous.

JSON Semantic Diff - Compare JSON by meaning, not just position.

Built for messy JSON with reordered arrays. JSON Semantic Diff infers likely object identity, supports composite keys and manual overrides, and suppresses positional noise so meaningful changes stand out. Everything runs locally in the browser.
