**What Is RAND Function In Excel?**

The

RAND function in Excelcreates evenly distributed random real numbers. These generated random values are between 0 and 1, so the values range is greater than or equal to 0 and less than 1.

The **RAND Excel Function **is a **Volatile function**. So, the values are recalculated every time the worksheet is opened or modified, or the calculation is prompted. As a result, the random numbers generated in the selected cells are unique and are not repeated in the same selection.

For example, we apply the **RAND Function **to calculate random numbers in cell **A1**.

Enter the formula ** =RAND(), **and press the “

**Enter**” key.

The output is “**0.7658**”, as shown above. A random number is generated between **0** and **1** without getting any input in the formula.

###### Key Takeaways

- The
**RAND Excel function**generates random numbers from 0 to 1. It can also generate random percentages from 0% to 100%. - Since it is a Volatile function, it generates a new value each time the worksheet is opened, or the formula is triggered.
- To calculate the random numbers between two numbers, we must use the following RAND formula,
**“**[*=a+ (b-a)*RAND ()*”.**a**and**b**can be any integers]. - We can use the
**RAND Function**and change the output cell format to “Time” to generate random time, just like random numbers.

**RAND() Excel Formula**

The Syntax of the **RAND Excel formula** is,

The formula does not have any arguments.

**How To Use RAND Excel Function?**

The **RAND Excel function **can be used in 2 methods, namely**,**

**Access from the Excel ribbon.****Enter the worksheet manually.**

**#1 – Access from the Excel ribbon**

Choose an empty cell for the result > select the **“Formulas” **tab > go to the “**Function Library**” group > click the **“Math & Trig” **drop-down > select the “**Rand**” function option, as shown below.

The ** RAND Excel formula** is inserted in the cell, and the

**“Function Arguments”**window instantly appears, as shown below. Since this function has no arguments, click “

**OK**”

**.**

**#2 – Enter the worksheet manually**

- Select an empty cell for the output.
- Type
**=RAND()**in the selected cell. [Alternatively, type “**=R**” and double-click the**RAND function**from the list of suggestions shown by Excel]. - Press the “
**Enter**” key.

**# Basic Example**

We will generate random numbers using the **RAND Excel **formula.

In the table, the data is,

- Column A contains the Output to be calculated.
- Column B contains the Formula for our reference.

The steps to generate the random numbers using the **RAND Function **are as follows:

__Step 1__**:** Select cell **A2**, enter the formula ** =RAND() **and press the “

**Enter**” key. The output is

**‘0.274’**, as shown below.

__Step 2__**: **Drag the formula from cell **A2** to cell **A5** using the fill handle.

The output is shown above. The formulas displayed in Column B are for our reference.

**[Note: **The **RAND function** generates random numbers between 0 and 1, so the above example returns random numbers between 0 and 1].

**Examples**

We will understand the **RAND in Excel **with some advanced scenarios.

**Example** **#1**

We will generate random numbers between 0 and 100 **using RAND Excel Function.**

In the table, the data is,

- Column A contains the Output to be calculated.
- Column B contains the Formula for our reference.

The steps to generate the random numbers using the **RAND in Excel **are as follows:

__Step 1__**:** Select **cell A2,** enter the formula ** =100*RAND()** and press the “

**Enter**” key. The output is

**‘52.150’**, as shown below.

__Step 2__**: **Drag the formula from cell **A2** to cell **A10** using the fill handle.

The output is shown above. The formula ** =100*RAND() **first generates the random numbers between 0 and 1, multiplies the result by 100, and returns the output between 0 and 100.

[**Note:** The **RAND Excel** **function** generates random numbers only between 0 and 1. However, we can build formulas like the above example and generate random numbers between different numbers].

**Example** **#2**

We will generate the random number between 10 and 20 **using RAND Function**. In this example, the formula used is ** “=a+(b-a)*RAND()”. **When we enter the two values, 10 and 20, the formula will then be

*“=10+(20-10)*RAND()”.*In the table, the data is,

- Column A contains the Output to be calculated.
- Column B contains the Formula for our reference.

The steps to generate the random numbers using the **RAND Excel** **function** are as follows:

__Step 1__**:** Select **cell A2, enter the formula** ** =10+(20-10)*RAND()** and press the “

**Enter**” key. The output is

**‘14.366’**, as shown below.

__Step 2__**: **Drag the formula from cell **A2** to cell **A10** using the fill handle.

The output is shown above.

[**Note:** Using the formula ** =a+ (b-a)*RAND()**, the

**RAND Excel Function**generates the random number between two integers, 10 and 20, as seen in the above example]

**Example** **#3**

We will generate random time **using RAND Excel Function.**

In the table, the data is,

- Column A contains the Output to be calculated.
- Column B contains the Formula for our reference.

The steps to generate the random time using the **RAND Excel function** are as follows:

__Step 1__**:** First, we will set **column A** to “**Time**” format. Choose column A > select the “**Home**” tab > go to the “**Number**” group > click the “**Number Format**” drop-down > select the “**Time**” option, as shown below.

** Step 2: **Enter the formula

**in cell A2 and press the**

*=RAND()***“Enter”**key. The output is

**‘06:34:05’**, as shown below.

** Step 3: **Drag the formula in cell

**A2**to cell

**A10**using the fill handle.

The output is shown above in the “**Time**” format.

**Important Things to Note**

- The
**RAND Excel function**reduces the speed of the workbook due to consistent recalculation of the randomly generated values. - To generate a set of random numbers in multiple cells, instead of dragging the formula, first, select the cell range for the output, enter the
**RAND() formula**, and then press the “**CTRL+ENTER**” keys in place of the “**Enter**” key. - To stop the auto-change in the
**RAND Excel function**, click on the result that we do not want to change. Then, in the Formula Bar, press the**F9**key [in some cases,**Fn+F9**] to convert the formula into its value.

**Frequently Asked Questions**

**What is the purpose of the RAND function in Excel?**

The purpose of the **RAND function in Excel** is as follows:

1. The **RAND** or **RANDBETWEEN** function in Excel generates a list of random numbers. It creates more values than we need, and we can delete some duplicates later.

2. We can convert formulas to values to prevent Excel random functions from recalculating.

3. The function removes duplicate values using Excel’s built-in tool or the advanced Duplicate Remover for Excel.

**How does the RAND function work in Excel?**

We can use the **RAND function **works** in Excel** as follows:
