Structural JSON diff vs text diff
A plain text diff highlights changed lines, so re-ordering keys or reformatting shows up as noise. This tool parses both sides and compares them structurally — by key and value — so you see only what actually changed: keys added, removed, or changed, each with its path. Both documents are parsed in your browser.
