# 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.

Enter the formula as an array formula. Hint: enter formula using keys Ctrl + Shift + Enter.

### Examples

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

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

### 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
