How can I compare a master part numbers list in one Excel
column or worksheet
against actual values in a second Excel column or
worksheet, and display the
missing part numbers that were not in the second column
in a new column or
worksheet?

For Example:
Part Number Master Part List Missing Parts

12A221316 12A221316 12A221333
12A221317 12A221317
