In large datasets, you often find duplicate values—data entries that occur more than once. You must handle those carefully to avoid any issues when processing volumes of information. The Excel dynamic array UNIQUE function returns a list of unique values in a range or list, and it supports different data types such as text, dates, and numbers.

You start by selecting a range or array from which you want to extract the unique values. Then, you can employ two optional arguments: by_col and exactly_once. The argument by_col allows you to compare values by row or by column. And the argument exactly_once specifies whether the values should only occur once or all distinct values should be listed.
