JSON Diff Viewer — Compare Two JSON Objects

Compare two JSON objects side by side and instantly highlight added, removed, and changed fields. Color-coded diffs make it easy to spot configuration changes, API response differences, and data migrations.

FAQ

How do I compare two JSON files?

Paste the first JSON in the left panel and the second in the right panel. Changes are highlighted: green for added keys, red for removed keys, and yellow for modified values.

What are common use cases for JSON diff?

Comparing API responses before/after a code change, reviewing config file updates, debugging data pipeline transformations, and auditing environment variable changes.

Does JSON diff care about key order?

No — the diff is semantic, not textual. { a: 1, b: 2 } and { b: 2, a: 1 } are treated as identical because JSON objects are unordered by definition.
