@Bookluvr18 I can’t really think of anything useful that doesn’t use some kind of code, sorry. The only thing I can think of is perhaps converting each letter in each square into a coordinate (e.g. 7C XS becomes [6,1a] & [5, 4b]*), then solve it as substitution (using find and replace in a text editor of some kind) for each grid ([5, 4b] becomes E, but [5, 4a] doesn’t, as that’s a different grid).
Not sure if that would take longer than just doing each letter manually anyway, but I hope it helps.

*I believe my grid was a different way around to the case file, so these may not be the correct coordinates
