I am sure this is a routinely run task but I am not sure the correct terminology of the task to search on it. I have have two different files, file "abc" has column A as "UPC" and column "E" as inventory qty. In file "#2" I have column "C" as "UPC", I want to take the column "E" from file "abc" and import it into file "#2" in a new column next to the corresponding "UPC" record. Is this called a look up? Can this task be automated in a macro?
