Periodically you may have a need to assign random numbers to an employee list, such as for raffle drawings or drug testing. In this article I’ll show how you can use the RANDBETWEEN function together with an Excel pivot table to pull a randomized assortment of employees.

The RANDBETWEEN function was introduced in Excel 2007 and has two arguments:

  2. Top – The largest random number that could be assigned

Thus a formula like =RANDBETWEEN(1,1000) would generate random numbers between 1 and 1,000. You may be familiar with the RAND function, which generates random numbers between 0 and 1. Thus historically Excel users would craft a formula such as =RAND()*1000 to generate random numbers.
