# JSON Diff

Compare two JSON documents and highlight the differences.

## What It Does

Compare two JSON documents and see what was added, removed or changed, key by key. Because both sides are parsed first, differences in whitespace and key order are ignored and only real changes are reported — which makes it far more useful than eyeballing two formatted blobs.

## Questions

### Does key order count as a difference?

No. Both documents are parsed and compared as structures, so reordering keys is not a change.

### Can it merge the two documents?

No. It reports differences. Merging is a separate decision that depends on which side should win, and that is a judgement the tool cannot make for you.
