The UNIQUE function returns a list of unique values in a list or range. For example:
Argument
Required
Description
array
Y
The range or array from which to return unique values
[by_col]
N
Is a logical value indicating how to compare; By row = false or omitted; By column = true
[occurs_once]
N
Is a logical value: only return unique values that occur once = true; include all unique values = false or omitted
Note:
The UNIQUE function is only valid when allowDynamicArray is true.
The UNIQUE function will return an array, which will spill if it's the final result of a formula.
An array can be thought of as a row of values, a column of values, or a combination of rows and columns of values.
