Lookup tablesSometimes, we have a code that we want it to be replaced

with a value

1/21/2009 CPSC203- Week1- Lab2 25

=LOOKUP(B4,F3:G7)

VLookupSearching for a certain text, e.g. student ID

1/21/2009 CPSC203- Week1- Lab2 26

We want to lookup student with Id 3000=VLOOKUP(3000,A5:B9,2)

Formula: VLOOKUP(Value, table, column Index)
