Leaderboard and Badging with Google Sheets

Many of us in the gamified education game have toyed with different leaderboards and badging systems over the years. I've often dreamed of having a system that does the tracking of XP, badges, and items automatically as I input scores, without having to navigate between spreadsheets copy/pasting data from one to the other. This dream also includes the ability to change ranking and badging systems relatively quickly so that if my students become bored with something I do not have to start from scratch each time. As I've kept toying with this idea, I've been discovering some new tricks on spreadsheets that have allowed me to come up with a template of sorts.
