How to use
Place the old and new JSON in the two inputs. Decide whether array order is meaningful before comparing.
Follow added, removed, and changed paths and inspect types as well as values. Ignoring order can hide an important reorder; choose the setting according to what the data represents.

{"a":1,"b":2}

{"a":1,"b":3,"c":4}Principles and limits
