What is the formula for comparing lists of data in Excel?

This formula in particular allows you to take a partial list with some blank data and compare it to a master list and retrieve the blank data. For example, let's say we have a list of 10 student names that we need Student ID's for, and the only point of reference that we have is a master list of all 200 students and their respective ID's. The formula allows us to match the name from our list to the master list, and bring a copy of the student ID to our list. Attached is a spreadsheet outlining these details in a more visual method.

As mentioned, your output will be the student ID's for all the students in our list.
