I'm playing around with a client-side js implementation of this at https://www.robosheets.com/

It's not production ready / launched yet, but it's getting there.

I'd be interested to finds (or really doesn't find) this useful :)

I wasn't able to figure out how to use the app, but I did want to drop in to say that I like how you've placed the "Upgrade to enable" notices in cells past a limited range.
