**What Is CHOOSE Function In Excel?**

The

CHOOSEfunction in Excel returns a value from an array based on a specified index number. It belongs to the category ofLookup & Referencefunctions. Users can use the ExcelCHOOSEfunction when building scenarios in financial models. Also, it gives excellent results when combined with functions such asINDEXandVLOOKUP.For example, consider the below image. The first table shows a list of car models, ranked by their sales figures.

Suppose we need to display the third-best-selling car in cell E1. Then, we can apply the Excel **CHOOSE** function in the target cell as depicted in the below image.

The **CHOOSE function result** in cell E1 shows the car model at the third position in the array of car models, as the index number mentioned in the function is **3**.

###### Key Takeaways

- The
**CHOOSE()**function returns a value from the value arguments based on the position of the value in the array. - I
**ndex_num**and**value1**are the mandatory arguments of**CHOOSE()**. While**index_num**can take a value from 1 to 254, we can supply a value of 1 to 254 to**CHOOSE()**. - While the
**CHOOSE()**function can be an alternative to nested**IFs**, we can use the function to generate random data and successfully do a left**VLOOKUP**. - When used with functions such as
**INDEX**and**MATCH**, the**CHOOSE()**produces excellent results.

**CHOOSE() Excel Formula**

The **CHOOSE Excel formula **is:

where,

**index_num**: An integer that indicates the value argument. This argument must be any value from 1 to 254 or a cell reference to a cell having a number between 1-254.**value1**,**value2,…**: The list of 1-254 values from which the**CHOOSE**function selects a value based on the specified**index_num**. They can be numbers, text, excel cell references, formulas, or text.

Below are a few aspects we must consider while using the **CHOOSE function syntax**.

- If the
**index_num**is**1**, the**CHOOSE()**output will be**value1**. Likewise, if the**index_num**is**2**, the**CHOOSE function**in excel**result**will be**2**, and so on. - If the
**index_num**argument is a fractional number, it gets truncated to the lowest integer. - If the
**index_num**argument is an array, every array element gets assessed when the**CHOOSE**excel function gets evaluated. - If the
**index_num**is a value below one or more than the number of entries in the value list, the function will return the**#VALUE!**error. - The value list contains individual values, cell references to cells containing the values, or cell range references, separated by commas.

While **index_num** and **value1** are mandatory arguments, the rest are optional.

**How To Use CHOOSE Excel Function?**

The steps to use **CHOOSE** excel function are:

- First, ensure we have the required arrays in the source data table.
- Next, select the target cell and enter the
**CHOOSE()**with the mandatory and required optional arguments. - Finally, press
**Enter**to view the result.

Here is an **CHOOSE function example** to understand the steps.

Suppose we need to display the 6^{th} color in cell D2 from the list of colors in the first table, with cell D1 displaying the index value, **6**, we need to use the following steps.

**Step 1: **First, select cell D2, type the below **CHOOSE** Excel function. Then, press **Enter**.

**=CHOOSE(D1,A2,A3,A4,A5,A6,A7,A8,A9)**

Alternatively, the above **CHOOSE function example** will work with the below formula:

**=CHOOSE(6,”Red”,”Blue”,”Green”,”Yellow”,”Pink”,”Brown”,”Magenta”,”Orange”)**

Here we directly provide the values as arguments to the **CHOOSE() **instead of entering the cell references to the values.

Likewise, we can use the Excel CHOOSE function to obtain the results.

**Examples**

Here are a few examples of how to use the Excel **CHOOSE** function.

**Example 1 – CHOOSE As An Alternative To Nested IFs**

Consider the below table. It shows the students’ aggregates and the grades legend.

Suppose we need to enter the grade for each student in column C, then we can use nested IFs with the below steps.

The formula in cell C2 would be:

**=IF(B2>=91,$F$3,IF(B2>=76,$F$4,IF(B2>=61,$F$5,IF(B2>=46,$F$6,$F$7))))**

And once we drag the Excel fill handle downwards to copy the nested **IFs** formula in cells C3:C11, the output will be:

However, we can use the **CHOOSE** function instead of the nested **IFs** function and make the formula more straightforward. The steps are:

**Step 1: **To begin with, select cell C2, and then, type the below **CHOOSE(), **and press **Enter** key.

**=CHOOSE((B2<=45)+(B2<=60)+(B2<=75)+(B2<=90)+(B2<=100),$G$3,$G$4,$G$5,$G$6,$G$7)**

**Step 2: **Next, drag the fill handle downwards to copy the formula in the cell range C3:C11.

In the above example, the **Excel CHOOSE function multiple conditions** define the **index_num** argument. Each condition will result in a **1** or **0**, depending on whether the condition holds. And then, all the five results gets added to give the **index_num** value. On the other hand, the remaining arguments form the value list, containing five values.

For example, the calculations of **CHOOSE Excel**

**function with multiple conditions**in cell C2 are:

**=(0+0+0+0+1,$G$3,$G$4,$G$5,$G$6,$G$7)**

**=(1,$G$3,$G$4,$G$5,$G$6,$G$7)**

**=A**

**Example 2 – Using CHOOSE With Arrays**

Here is a table with three arrays, **Book**, **TV Show**, and **Movie**.

And suppose we need to update column E using the three arrays. Then we can use the **CHOOSE** excel function.

The steps used are as follows:

**Step 1: **First, select cell E2, type the below **CHOOSE()**, and press **Enter**.

**=CHOOSE(2,A2:A7,B2:B7,C2:C7)**

**Step 2: **Then, drag the fill handle downwards to copy the formula in the cell range E3:E7.

In the above example, each value in the value list is an array. And as the **index_num** is **2**, the second array gets populated in column E.

**Please Note: **If you copy the formula in cells after cell E7, the cells will have a value of **0** as the second array in the source data in the range B2:B7.

**Example 3 – Generate Random Data**

If we require to generate random data, we can apply the Excel **CHOOSE** function, with the **RANDBETWEEN()** used as the **index_num** argument.

For example, the below table shows a list of players. We need to randomly allot a team, **A**, **B**, **C**, or **D**, to each of them with the following steps.

The steps used to obtain values with CHOOSE function are as follows:

**Step 1: **To begin with, select cell B2, type the below **CHOOSE()**, and press **Enter** key.

**=CHOOSE(RANDBETWEEN(1,4),”TEAM A”,”TEAM B”,”TEAM C”,”TEAM D”)**

**Step 2: **Drag the fill handle downwards to copy the formula in the range B3:B11.

There are four teams, **TEAM** **A**, **TEAM B**, **TEAM C**, and **TEAM D**. So, the **index_num** can be any value from **1** to **4**.

The **RANDBETWEEN() **randomly generates an index number (between 1 to 4) every time the **CHOOSE()** executes. And depending on the generated **index_num**, the **CHOOSE()** returns the corresponding team name at the specific position in the supplied array.

**Example 4 – CHOOSE Formula To Do A Left VLOOKUP**

Consider the below table showing employee details.

Let us assume that we have to display the employee ID of an employee mentioned in cell F1 in cell F2. In such a scenario, a left **VLOOKUP** will not work; it will throw an error as shown in the following image.

Instead, we can apply the left **VLOOKUP** with the **CHOOSE** function in cell F2 to get the desired result.

**Step 1: **Select cell F2, type the below **VLOOKUP** function containing the **CHOOSE()**, and press **Enter**.

**=VLOOKUP(F1,CHOOSE({1,3},C2:C7,B2:B7,A2:A7),2,0)**

The term **{1,3}** ensures the columns A and C, **EMP ID** and **Employee**, get selected. And the **CHOOSE()** swaps the columns, making **Employee **and** EMP ID** columns the new columns A and B.

And since the **CHOOSE()** gives two columns as output, the **VLOOKUP** range becomes 2 instead of **3**.

**Example 5 – CHOOSE Function For Selecting Month**

Let us assume that we need to enter the order month in column C in the below table.

Using the Excel **CHOOSE** function, we can enter the order months, deriving them from the dates in column B.

**Step 1: **First, select cell C2, type the **CHOOSE()** mentioned in the Formula Bar, and press **Enter** key.

**Step 2: **Next, drag the fill handle downwards to copy the formulas in range C3:C11.

The **MONTH() **is the **index_num** in the above **CHOOSE()**. It takes the date as the argument and returns the month number based on the date. Then the **CHOOSE()** returns the month name depending on the evaluated month number.

Thus, using the **CHOOSE()**, we can select months.

**Things to Remember**

- The Excel
**CHOOSE**function helps pick a value from an array of values, thus making it useful while selecting scenarios for developing powerful financial models. - The
**CHOOSE()**will return the**#VALUE!**error if the**index_num**argument is not an integer or a cell reference to a numeric value. We might also see this error if the**index_num**is lesser than one or greater than the number of value arguments supplied to the function. - The
**CHOOSE()**will return the**#NAME?**error if the value arguments are text values without double quotes or the cell references are invalid.

**FAQs**

**When to use Excel CHOOSE function?**

We can use **CHOOSE** function when we need a specific value from an array of values. We can apply the function when;

● Selecting a month.

● Using it as an alternative to nested **IFs**.

● Using it with **RANDBETWEEN()** to generate random data.

● Performing a left **VLOOKUP**.

**Why use Excel CHOOSE function?**

The **Excel CHOOSE function** can help us select a specific value from an array of 254 values, with the key benefit being that the function returns a value or a cell reference to the value.

On the other hand, creating scenarios is a critical step in developing financial models. The **CHOOSE()** enables us to select the required scenario from a set of scenarios according to your requirement.

**How to use Excel CHOOSE function to return a custom day?**

We can use **CHOOSE** excel function to return a custom day by following the below steps:

Consider the below table containing custom dates in column C.

The steps to determine the custom day from the date in each cell, using the **CHOOSE()** are:**Step 1: **Select cell D2, type the below **CHOOSE()**. Then, press **Enter** key.**=CHOOSE(WEEKDAY(C2),”Sunday”,”Monday”,”Tuesday”,”Wednesday”,”Thursday”,”Friday”,”Saturday”)****Step 2:** Next, drag the fill handle downwards to copy the formula in the range D3:D11.

In the above example, the **CHOOSE()** contains custom days as the value arguments. The **WEEKDAY() **takes a date as an input and returns the day of the week as a number. The **CHOOSE()** considers the **WEEKDAY()** output as the **index_num**, based on which it returns the custom day for the specific date.
