I have 2 Excel files and I'd like to check if for each row in excel file A I have a row that matches on the primary key (same primary key in each files and is composed of 4 columns) and on a certain amount of other fields (not all the non primary key fields just some of them). However if the conditon isn't respected I'd like to see if there is no row in excel file B with this combination of primary key or if there is a difference in the additional fields to check (and if so, which fields ?). I've tried to use Power automate to do this (I prefer a cloud based solution for this) but my Excel files are too large (about 20000 lines each). Any help would be greatly appreciated 🙂
I tried to apply this method:
I get that it's because of the apply to each loop but I really have no idea how to do this without any loops. So if you know how to majorly decrease the execution time i'm very interested 🙂
PS: Sorry for any grammatical errors, I'm not a native English speaker.
Thank you for your answer but I'm failing to see how I can use this technique to compare my two excel files field by field because in the video that you linked they only check if all the IDs from Excel file B are in Excel file A and I wanna check that for a certain ID present in the two files that they aren't any differences on like 3 or 4 fields between the 2 records (If there is a difference then add the row of Excel file A in a new Excel file.

Get your data into Power Automate. Use select to create a column with the primary key concatenated from the other four columns. Then use filter functions to compare lists:

You basically want to avoid loops with your amount of data.
