I have spreadsheet: https://docs.google.com/spreadsheets/d/19GrXAFLpv6jz9OzDum-fyfP_m-RZFCNrQ0rr1vd5bYI/edit?usp=sharing
I want to count percent of wins(W) in C column and write it to C1 cell. I plan to add many rows.
I know VBA little bit, but not found how to use it inside Spreadsheet.
How to use VBA there?
And how to do this with fuction button?
