I have two columns of numbers. I want to know the numbers that do not have a
match or are not in both columns. But I need all of each column to be
compared to all of the other column...not cell by cell. It would be great if
I could pull out the differences and put them in a different column. Looking
at two long lists of numbers to pull out the different number is very time
consuming! Thanks for any help you can give me!
 
To check column A against column B:
=IF(ISNUMBER(MATCH(A2,B:B,0)),"",A2)

vice versa:
=IF(ISNUMBER(MATCH(B2,A:A,0)),"",B2)

Any number listed has not been found in the corresponding column.
