JSON Diff

Compare two JSON documents and see exactly which keys were added, removed or changed.

A JSON diff walks two documents in parallel and reports every path where they differ — keys added, keys removed, values changed, and values whose type changed. Arrays can be compared by position or as sets, and the result is also emitted in JSON Patch form.

Frequently asked questions

Why does my diff show changes when the files look the same?

Usually key order or whitespace. Object key order is not significant in JSON but a text diff treats it as a change — sorting both documents first removes that noise and leaves only real differences.

How to use the json diff

  1. 1Enter or paste your first json.
  2. 2Enter or paste your second json.
  3. 3Turn "Ignore array order" on or off as needed.
  4. 4The result appears immediately — copy or download it.
