Sorting columns


Is there any way to sort a column? I need to sort the call signs for dupes. And no, the DUPE function will not work for this, as the times may vary, so no dupe. I was in a local club  (100 + members) for the past ten days seeing who could make the most contacts. Now I've got to get rid of the dupes. Any constructive will be appreciated.
