Note: for a more detailed explanation of random numbers without duplicates, see this example. INDEX then returns the first 10 names in a spill range like the original formula. Which is returned to the INDEX function as the row argument. In either case, RANDARRAY will return 10 numbers in an array that looks like this: To create a random number between any two numbers that you specify, use the following RAND formula: RAND () ( B - A )+ A. Generate random numbers between two numbers. Example Copy the example data in the following table, and paste it in cell A1 of a new Excel worksheet. The largest integer RANDBETWEEN will return. The smallest integer RANDBETWEEN will return. The COUNTA function is used to get a dynamic count of names in the list, but we could replace COUNTA with a hardcoded 100 in this case with the same result: =INDEX(names,RANDARRAY(10,1,1,100,TRUE)) For instance, if you want to get random numbers between 0 and 10, including 10, the right formula is RAND ()11. Syntax RANDBETWEEN (bottom, top) The RANDBETWEEN function syntax has the following arguments: Bottom Required. Working from the inside out, we use RANDARRAY to get 10 random numbers between 1 and 100 like this: RANDARRAY(10,1,1,COUNTA(names)

This is an excellent use case for the RANDARRAY function, which can create a random set of integers in a given range. However, the trick in this case is that we don't want a single name at a known location, we want 10 random names at unknown locations between 1 and 100.

For example, to retrieve the fifth name from the list, we use INDEX like this: =INDEX(names,5) At the core, this formula uses the INDEX function to retrieve 10 random names from a named range called names which contains 100 names. To get the Random Generator add-in for Excel, you can go to the Microsoft AppSource portal and simply search for the specific add-in by typing the name or the.
