Remove Duplicates from a list

In Microsoft Office Excel 2007, you have several ways to filter for unique values or remove duplicate values:

To filter for unique values, use the Advanced command in the Sort & Filter group on the Data tab.

To remove duplicate values, use the Remove Duplicates command in the Data Tools group on the Data tab.

To highlight unique or duplicate values, use the Conditional Formatting command in the Style group on the Home tab.
