Today, let’s explore how to use the RANDBETWEEN function to generate random numbers within a specific range—all from a single formula! This dynamic function is ideal for situations where you need to assign random codes, create test data, or run simulations efficiently.

Imagine you have a list of employees and want to assign each of them a unique code number instantly. With RANDBETWEEN, the process is straightforward—no need for manual selection or estimation.

Here’s how it works:

• The RANDBETWEEN function generates a random whole number between two defined limits (like 1000 and 9999 for 4-digit codes).

• Easily produce random data for testing or training.

• Assign unique codes or IDs in a short amount of time.

• Set your range to control the output (e.g., 18 to 29 or 1000 to 9999).

This approach is particularly useful for:

• Generating random employee IDs or codes

• Creating sample datasets for testing

• Running simulations or randomized experiments

• Simplifying data entry tasks that require unique numbers
