UNIQUE

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

Syntax

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.

Examples

Given the data table below, the examples returns unique occurrences of grades and age.

 A B C D E Name Grade Age Distance Weight Andy 3 9 150 40 Betty 4 10 1000 42 Charles 3 10 300 51 Daniel 5 11 1200 48 Eva 2 8 650 33 Frank 2 7 300 42 Greta 1 7 200 36 Harry 3 9 1200 44 Irene 2 8 1000 42

Example 1

{=UNIQUE(B1:C10,FALSE(),FALSE())} returns the array below. The grades and ages of the rows with name Andy and Harry are returned only once. The same for rows with name Eva and Irene.

 Grade Age 3 9 4 10 3 10 5 11 2 8 2 7 1 7

Example 2

{=UNIQUE(B1:C10,FALSE(),TRUE())}, with Uniqueness as TRUE. Returns the array below with the rows of Andy, Harry, Eva and Irene omitted because their combined grades and ages are not unique.

 Grade Age 4 10 3 10 5 11 2 7 1 7
