How to compare two JSON documents

What it compares

The diff checks objects, arrays, and primitive values after both sides are parsed as JSON.

How to use it

  • Paste the original JSON on the left.
  • Paste the updated JSON on the right.
  • Review added, removed, and changed paths.

Useful for developers

  • Compare API responses.
  • Check configuration changes.
  • Review small JSON payload differences before debugging deeper.

Diff notes

The comparison focuses on parsed JSON values, so property order and whitespace are ignored while value, type, object, and array changes are reported by path.

Frequently Asked Questions

Does it support nested values?

Yes. Differences include nested object and array paths.

Does key order matter?

Object key order is not treated as a change by itself.

Can I compare invalid JSON?

No. Both inputs need to parse as valid JSON first.

How are array changes shown?

Arrays are compared by index, so inserting an item near the start can show several changed positions after it.
