![]() Well, what do we know about the random number generator in Excel? This is the reason why it has never been documented and will hardly ever be. What it means for you is that, in theory, random numbers generated by Excel are predictable, provided that someone knows all the details of the generator's algorithm. Like most computer programs, Excel random number generator produces pseudo-random numbers by using some mathematical formulas. Let's take a closer look at the Excel random generator algorithm so that you know what you can expect from it, and what you cannot. But don't write it off immediately :) Pseudo-random numbers produced by the Excel random functions are fine for many purposes. ![]() Advanced Random Number Generator for ExcelĮxcel random number generator - the basicsĪlthough the Excel random generator passes all standard tests of randomness, it does not generate true random numbers.Prevent Excel random functions from recalculating.Generate random numbers without duplicates (unique random numbers).Create random text strings and passwords.Generate random numbers with decimal places.Excel random number generator - the basics.Of course, we won't rely on such "exotic" techniques in this tutorial and focus on what Excel random number generator has to offer. And because it has always been in demand, various methods of creating random numbers have existed since ancient times, such as flipping coins, rolling dice, shuffling playing cards, and so on. Randomness has a variety of different applications in cryptography, statistics, lottery, gambling, and many other fields. In plain English, random data is a series of numbers, letters or other symbols that lacks any pattern. The tutorial explains the specificities of the Excel random number generator algorithm and demonstrates how to use RAND and RANDBETWEEN functions to generate random numbers, dates, passwords and other text strings in Excel.īefore we delve into different techniques of generating random numbers in Excel, let's define what they actually are.
