I've updated Yandere Simulator Resources Wiki - the JSON and XML page there has all the info you need.

As for club leaders, you'll have to switch the designs/places of the characters.

The best option is to make a backup copy of the JSON file. However, a bad one WILL NOT permanently corrupt your build.
