Choose and Match Functions

The Excel Choose and Match functions both work with arrays of data.

• The Choose function receives a position and returns the value that has this position in the array.
• The Match function receives a value to lookup, and returns the postion of the value in the array.

## Basic Description

The Excel Choose function returns a value from an array, that corresponds to a supplied index number (position).

I.e. the Choose function returns the n'th entry in a given list.

The syntax of the function is:

CHOOSE( index_num, value1, [value2], ... )

where the arguments are as follows:

 index_num - An integer, which specifies the index of the item to be returned. value1, [value2], ... - A list of one or more values that you want to return a value from.Note that these must entered as individual values (or references to individual cells containing values).

In current versions of Excel (2007 and later), up to 254 value arguments can be supplied to the Choose function. However, in Excel 2003, you can only supply up to 29 values to the function.

## Excel Choose Function Examples

### Example 1

Imagine you are working on the spreadsheet below and you want to set the cells in Column B to have the following values, depending on the value of the corresponding cell in Column A.

1 - red; 2 - blue; 3 - green; 4 - brown

The Excel Choose function can be used to assign the correct value to the cells of Column B, as shown below:

Formulas:
AB
14=CHOOSE( A1, "red", "blue", "green", "brown" )
22=CHOOSE( A2, "red", "blue", "green", "brown" )
33=CHOOSE( A3, "red", "blue", "green", "brown" )
41=CHOOSE( A4, "red", "blue", "green", "brown" )
Results:
AB
14brown
22blue
33green
41red

### Example 2

The Excel Choose function can also return cell references, as shown in the following example. In this case, the reference that is returned from the Choose function is then provided to the Excel SUM Function.

Formulas:
ABC
1103=SUM( CHOOSE( B1, A1, A1:A2, A1:A3, A1:A4 ) )
211
312
413
Results:
ABC
110333
211
312
413

In the example above, the Choose function returns the cell reference A1:A3. This is then passed to the SUM function which calculates the sum of the values in the cell range A1:A3 and returns the value 33.
