# JSON Diff

Category: General dev
Where it runs: Runs locally (nothing you enter is uploaded)

Paste two JSON documents and get a table of every path that was added, removed or changed, with old and new values. Useful for comparing an RDAP or API response before and after a takedown.

## Example input

Domain record before a takedown (JSON A)

```
{"domain":"login.example.com","status":"active","ns":["ns1.example.net","ns2.example.net"]}
```

JSON B is the same record after the takedown: the diff shows the changed status, the shorter name-server list and the added ip key.

## FAQ

### How are differences found?

Both inputs are parsed and walked key by key: each path is reported as added, removed or changed (old → new), nested objects are followed (action.ttl) and arrays are compared index by index (ns.1). Key order is ignored, and equal documents show Identical.

### What are the limits?

Array items are matched by position, so inserting one item reports every later index as changed. Compare objects or arrays: two plain top-level values such as 5 and 6 are reported as Identical, and an array is not told apart from an object with the same index keys.

### Is my JSON uploaded?

No. Parsing and comparison run in your browser and nothing is sent.
