In Excel, there are several ways to filter for unique values—or remove duplicate values: Show
Filtering for unique values and removing duplicate values are two similar tasks, since the objective is to present a list of unique values. There is a critical difference, however: When you filter for unique values, the duplicate values are only hidden temporarily.

A duplicate value is one in which all values in at least one row are identical to all of the values in another row. A comparison of duplicate values depends on the what appears in the cell—not the underlying value stored in the cell. For example, if you have the same date value in different cells, one formatted as "3/8/2006" and the other as "Mar 8, 2006", the values are unique.
