# Find Out How to Generate Unique Random Numbers in Excel

Excel allows us to generate unique random numbers in Excel using the RAND and RANK functions. This step by step tutorial will assist all levels of Excel users to find out how to generate unique random numbers in Excel.

Figure 1. The final result of the formula

## Syntax of the RAND Formula

The generic formula for the RAND function is:

`=RAND()`

The function returns a random decimal number between 0 and 1 and has no parameters.

## Syntax of the RANK Formula

The generic formula for the RANK function is:

`=RANK(number, ref, [order])`

The parameters of the RANK function are:

• number – a number which we want to rank
• ref – a list of numbers for ranking
• [order] – 1 for ascending or 0 for descending order. This parameter is optional, if it’s omitted, the default order is descending.

## Set up a Random Team Generator

First, we need to get a random number in column B

The formula for RAND in B3 looks like:

`=RAND()`

To apply the formula, we need to follow these steps:

• Select cell B3 and click on it
• Insert the formula: `=RAND()`
• Press enter
• Drag the formula down to the other cells in the column by clicking and dragging the little “+” icon at the bottom-right of the cell.

Figure 2. Using the RAND formula

When we get a random number we can rank them in column C.

The formula for RANK in C3 looks like:

`=RANK(B3, \$B\$3:\$B\$14)`

The number parameter is the cell B3. The ref parameter is the range \$B\$3:\$B\$14. We must fix the range, as it’s not changing when the formula is copied down the cells.

To apply the formula, we need to follow these steps:

• Select cell C3 and click on it
• Insert the formula: `=RANK(B3,\$B\$3:\$B\$14)`
• Press enter
• Drag the formula down to the other cells in the column by clicking and dragging the little “+” icon at the bottom-right of the cell.

Figure 3. Using the RANK formula

Now we have 12 unique random numbers in column C.
