I am wondering if and how this can be done:
I have a spreadsheet that has three columns for Highschool name, State and CEEB code.
As of now, we have to manually look up the CEEB code and fill them in.
Is there a way i can give excel the entire list of all HSs and CEEB codes, so when I enter a High School and hit tab, it fills in the CEEB code automatically if it exists in the list provided to excel.
