Hi Guys,
I would like to ask for your ideas on how I am going to compare the excel files provided in a list. A list is given to us (10 IDs or more) that is being manually check in the shared drive. I would like to have it automated by reading all IDs until nothing to compare. The output should look like this:

This is the sample list from our partner (attaching the ID Compare). This means Column A vs Column B :

Any additional space is considered mismatch.
Please let me know if you have any question. Hoping you could help and give me ideas on this.
Thanks,
Kamen
