This form allows you to generate randomized sequences of integers. The randomness comes from atmospheric noise, which for many purposes is better than the pseudo-random number algorithms typically used in computer programs.
Enter a range of numbers (like 1-49) or a list of numbers to randomize (like 10 20 30 40 50). You can also mix ranges and list (like 1-10, 90-100). You can also add alphanumeric lists or words (like a,b,c or apple, orange, banana).

The RANDARRAYfunction, introduced in Excel 365, generates arrays of random numbers. For example, if you want 20 unique random numbers between 1 and 200, you can use this formula: Here’s what each part of the formula means: 1. 10is the number of rows (how many numbers you want). 2. 2is the number of columns (usually you only need 1). 3. 1is the mini...
The UNIQUE function, available in Excel 365 and Excel 2021 versions, returns a list of unique values from a given dataset or cell range. UNIQUE function can be combined with RANDARRAY function to produce random numbers without repetition. Here’s an example formula: This formula does the same thing as the previous one, but it uses the UNIQUE functio...
The RAND functiongenerates a number between 0 to 1. Use the formula if you want to generate unique decimal numbers. The RANDBETWEEN functiongives random numbers between two given numbers. For example, if you want to get the integer numbers between 1 and 100, you can use the formula below. Here, 1 is the bottom argument and 100 is thetopargument. Th...
Furthermore, you can use the RANK function which returns the relative size of a number based on the given list of numbers. Before doing that create a list of random decimal numbers utilizing the RAND function. Here, B5 is the starting cell of decimal numbers and B5:B15is the cell range for decimal numbers.
Let’s say you want to generate random numbers without repetition from 10 to 50. First, create a list of numbers between 10 and 50 using the RANDBETWEEN function. Now, use the formula below- Here, B5 is the starting cell of random numbers andB5:B15is the cell range for decimal numbers. The COUNTIF function is counting each random number that is avai...
We can produce random integer numbers without repetition using the combination of the LARGE and MATCH functions. The LARGE function returns the kth largest value in a given cell range or dataset. Here, $B$5:$B$15 is the cell range for random decimal numbers that are found using the RAND function, ROW(B1)refers to row number 1. Use the following for...
If you don’t like using formulas, you can use an Excel add-in called the Analysis ToolPak. This add-in has a random number generator that can create unique random numbers. To use the Add-ins, follow the steps below. ⇰ Go to File >Options. ⇰ Click on the Add-ins and select Excel Add-ins from the drop-down list and pick the option Go. ⇰ In the Add-in...
RANDOM.ORG is a true random number service that generates randomness via atmospheric noise. This page contains frequently asked questions (and answers!) related to the service. Section 1: Questions about the Service and Software. Q1.1: I use RANDOM.ORG a lot. How can I show my appreciation? Q1.2: Is the source code for the generator available?
