UNIQUE

Returns the array of unique values from a range or array of values.

Syntaxe

UNIQUE(Array, [By col], [Uniqueness])

Array: the range or array from which to return unique values.

By col: (optional) a logical value that indicates how to compare data: TRUE - compares data horizontally for a match of all cells in each column, across all columns. FALSE or omitted (default) - compares data vertically, for a match of all cells of each row, across all rows.

Uniqueness: (optional) A logical value that defines which values are considered unique. TRUE returns values that occur only once. The default is FALSE or omitted, which returns all distinct values in the range or array.

The UNIQUE function must be entered as an array formula.
