Where “names” is the named range C5:C14, and “class” is the named range B5:B14. Note: this is an array formula and must be entered with control + shift + enter. Note MATCH is set up to perform an exact match by supplying zero for match type. For lookup value, we have: The LEN function returns an array of results (lengths), one for each name in the list where class = “A” from cell F5 : This effectively filters out all of Class B, and the MAX function then returns the largest value, 8. To construct a lookup array, we use the same approach: And get the same result: After LEN and MAX run, we have a MATCH formula with these values: MATCH then returns the position of 8 in the list, 3, which feeds into INDEX like this: Finally, INDEX dutifully returns the value in the 3rd position of names, which is “Jonathan”.
