Have two tables/spreadsheets in Access/Excel

[Koenigsegg]

They're lists of customers, with their name, phone number, address, etc..is there a way to know which customers appear on both lists?

You can create a query in Access to check.

Import the lists into Access and then create an inner join query (both sides are equal) on the customer name and phone-number.
