Compare with another JSON

Paste the JSON to compare with the current output (objects by key, lists by position).

Fix JSON tries to fix common problems automatically before formatting:

Trailing commas
Missing commas between items ({"a": 1 "b": 2})
Single quotes instead of double quotes
Unquoted keys
// and /* */ comments
True/False/None (Python style)
Whole JSON in quotes ("{...}") or serialized twice
Serialized JSON inside a field ("payload": "{\"a\":1}") becomes an object
A snippet copied from the middle of a body ("key": value without { }, or cut off inside a string)
Empty values ({text:,...} becomes "")
Several loose objects ({...} {...}) become an array ([{...}, {...}])
