Generate a Unique List of Random Numbers in Excel With a Simple Formula

Create a list of unique random numbers in Excel with a simple formula that is easy to use and change - this works in older versions of Excel as well as Excel 365.

In this tutorial I show you 4 different formulas for generating unique lists of random numbers in Excel - this includes simple methods and more complex methods that allow you to set the minimum and maximum possible values as well as simple methods for simple lists that just need to appear in random order.
Everything in this tutorial should work for Excel versions back to 2007, or at least 2010, but let me know in the comments if you run into any issues.
As usual, make sure to download the file for this tutorial so you can follow along or just copy/paste the formula and use it as you want.

    Excellent job. Easy to understand. The cool thing about the Microsoft 365 versions is: You can have a large set of master data and use INDEX MATCH or other lookup functions to create random smaller data sets Just match the random number to a position sequence

    Completely agree! And Match really is an amazing function too, even when used in VBA! (Just added some great features to the VBA course I'm finishing, all thanks to Match.)

    Although random numbers are not something I would (typically) use on the job I really appreciate the insights into formula creation. Thank you Don!

    You're very welcome Dave! Oddly enough, this question about random numbers is one of the most common that I get asked, along with drop down lists.

    It can be a combination of 2 , 3 and 4 digit code

    Great video! Old and new school. A trick that I use when I generate random nr. to make them stop but keep them where they are. For ex: in B2 put "y" , in cell C2 =IF(B2="y",RANDARRAY(10,,1,100,1),C2#) . If we change B2 with "n" , will stop recalculating. New set of data? back to "y". Hit F9...F9....Like to keep a particular set, change B2 to "n" . Obs. If circular reference error, we need to go in Options , Formulas , tick ..Enable iterative calculations. Also could be cool to generate random words, random list selection.😉✌✌

    Interesting point! It seems that if you simply leave B2 blank it also won't recalculate.

    @@abbottkatz8830 It makes sense, recalculates ONLY for "y", I did it on purpose . Is easy to change for different behavior, as anybody likes.

    No worries, check this week's tutorial and it might help out a bit! There, I break-down 5 techniques for making advanced formulas and then combine them to make the biggest formula from this tutorial. I'm not saying it is an easy tutorial, but it might help clear things up a little.
