RAND Function in Excel – Generate Random Numbers

The RAND function in excel is an in-built mathematical excel formula useful for generating numbers randomly in excel.

In this tutorial, we would learn how to use the RAND formula in excel for generating random numbers in excel.

What is the Use of RAND Function in Excel

The excel RAND formula is an in-built math/trig excel formula which is used to generate and return evenly distributed random number between 0 and 1. Therefore, the result of this function is a random decimal number that lies between 0 and 1.

This function can be either directly used in an excel cell or can be used as a part of another excel formula.

Syntax and Arguments


There are no arguments or parameters of the RAND excel formula.

Using RAND Function in Excel with Example

Let us first take some simple example to understand how the RAND formula works in excel.

In this section, we would learn two ways to generate random numbers in range of cells.
