ANALYZER
JSON Diff Viewer
Paste two JSON objects and instantly see what was added, removed or changed. Perfect for comparing API responses, config versions and data migrations.
How it works
1
Paste both JSONs
Paste the original JSON on the left and the modified version on the right. You can also load examples.
2
Flat key diff
Both objects are flattened to dot-path keys (e.g. user.profile.name) so nested differences surface immediately.
3
Color-coded results
Green = added, red = removed, yellow = changed, grey = unchanged. Toggle unchanged rows as needed.
