Debug Unexpected JSON Changes
Pinpoint why a JSON object isn't what you expected.
💡 A structural diff (not line-by-line): it walks both objects and reports exactly which paths were added, removed, or changed — even deep inside nested objects and arrays. Everything runs in your browser.
debugging tips

Array elements are compared by index, so reordering shows up clearly.
Nothing is uploaded.
