Feasibility of an API script?

Hi everyone!  Wondering if something is possible.  I'm not particularly code savvy, so the idea of writing or rewriting character sheets is a bit beyond my skillset (it seems).  I am playing a system with several mods to the base system and character sheets for the system don't work for me.  I'd like to just create character sheets in something like Google Sheets, then have a list of actions characters could take.  If they take action X, the modifiers for the die roll are pulled from the google sheet for that character/player.  Is that even a rational approach? 

There's no way to get information from google sheets into roll20, other than using copy and paste, so it's not feasible. You might be able to do it by writing a browser extension that all your players install, but creating browser extensions is another skillset entirely.
