I still have a roll20 sheet from a few years ago that was developed during the Google+ days, but it's woefully out of date version-wise and now a little buggy after some updates to the roll20 API as far as I can tell. Also it requires a premium account 'cos it's literally just a bundle of code dropped into the custom sheet setup.
I am however going to be doing a small update to A NOCTURNE soon to correct some spelling mistakes, rules inconsistencies, etc. that've been caught in testing and proofreading, and with that update I'm going to see if I can put together some handy Google Sheets, because I too am currently doing 100% of my gaming online and know how handy these things are :)
