The basic problem:
How do I find duplicate records in one column and how to automatically remove them along with the entire line, but while one record was retained?
The easiest finally – built Excel functionality
When using Excel version 2007, built functionality can be used to remove duplication.
The command is on tab Data, a group Data Tools;
icon Remove duplicates.
