Compare two google sheet folders

Hello, I would like to compare two Google Sheet files. I’m a beginner and was using Make.

Here are my settings:

The values ​​that I wish to compare are extracted from my 2 files.
Now I want to find the differences between the two, which module should I use to do this?

Thanks in advance

Can you explain further are you looking to find subtracted difference between the values

Values ​​are shoe sizes. I want to find the difference between table 1 from yesterday, and table 2 from today, in order to keep my stock up to date.

table 1 result from yesterday :

table 2 result today :

we notice that the 36 is missing for the first line, and the 42 for the second, otherwise the others are identical.

I would like the final result to really highlight the differences between the table of yesterday and today, knowing that the differences can go in the other direction, for example for the first row, size 42 could come back into stock.

I hope these explanations will suit you.
