>>35890128this has been possible for a decade, the biggest problem is that to get the actual twitch data, you need a token which you can't get from these channels (without their permission). I played around with it more and at the very least the other sites allow you to call for some data via API that can fill out some neat statistics by the press of a button (at least CCV and followers seem marginally useful), although this too isn't live (it would be too much traffic and i don't think that spreadsheets have that functionality to begin with).
I'm gonna play around with it more, when i have time.
