7. VLOOKUP

In the example below, the VLOOKUP function finds the comment for the state that has a serial number of 5. Here is the breakdown. First, Excel takes the value 5 (E10) to find a match in the left-most column (column B). Second, it identifies imaginary columns (1, 2, 3, 4) in your defined range (B3:E8). Third, when it finds a match of SL 5, the function returns “BAD” from the comment column (4).
