As long as you have some column within the data which is a unique
reference (like an employee number, or stock code) then you can use
the MATCH function to see if the item in a particular record is
contained anywhere in the other data set - the formula is copied down
and would return something like "not present" if there is no match. A
similar formula can be used in the other data set to see if those
records are contained within the first data set. Then it is just a
matter of applying autofilter to the data sets to check for "not
present" to determine the unique values.

Hope this helps.

Thanks if anyone can help
