Just use a COUNTIF ! Much faster to write and calculate than the other suggestions.
EDIT:
Say you cell A1 should be 1 if the value of B1 is found in column C and otherwise it should be 2. How would you do that?
I would say if the value of B1 is found in column C, then A1 will be positive, otherwise it will be 0. Thats easily done with formula: =COUNTIF($C$1:$C$15,B1)
, which means: count the cells in range C1:C15
which are equal to B1
.
You can combine COUNTIF
with VLOOKUP
and IF
, and that's MUCH faster than using 2 lookups + ISNA. IF(COUNTIF(..)>0,LOOKUP(..),"Not found")
A bit of Googling will bring you tons of examples.
