If you like this kind of degeneracy, I tried AoC in Google Sheets this year.

I only made it to Day 6, and not even both stars every day. I'm pretty confident my Day 7 solution is correct, but I hit per-cell character limits on longer inputs.

Enjoy :) oh but don't open it on mobile, some sheets crash the app
