JSON Diff Tool

Compare two JSON objects side by side. Our diff tool performs a deep structural comparison, highlighting exactly what was added, removed, or changed — down to individual values and array items.

How It Works

Paste original JSON in the left editor
Paste modified JSON in the right editor
See structural differences highlighted below
Color-coded: green = added, red = removed, amber = changed

Frequently Asked Questions

What kind of diff does the tool perform?

It performs a deep structural comparison, not a text diff. This means it compares the actual JSON values and structure, showing you exactly what was added, removed, or changed at each path.

Can I compare JSON from different APIs?

Yes. Paste the first JSON response in the left editor and the second in the right editor. The tool will show all structural differences between them.
