This can be found in your formula builder, or you can quickly enter it manually: =randbetween(x,y), in which “x” is the bottom number and “y” the top number. To generate numbers between 0 and 50, your syntax should look like this: =rand()*50.įor generating random numbers in absolutely any range of your choosing, you will use the RANDBETWEEN function.
You can drag the fill handle to the range that you want to contain this formula:įor generating numbers between 0 and numbers greater or less than 1, modify the RAND syntax in the following way: =rand()*x, in which “x” is a number of your choosing. Tab over and a number between 0 and 1 will be generated in the cell this is what RAND does, every time. It will be entered into the cell you preselected. Several options should appear, but the ones in which we are most interested are RAND and RANDBETWEEN. Type in “rand” in the search bar and hit enter. To locate the Formula Builder, click on the Formulas tab on your Ribbon bar (the Ribbon bar is the green (Excel 2011) bar with a Home tab on its extreme left side):įind and click on the Formula Builder button that appears below. Even if you decide to enter RAND manually, the Formula Builder is an invaluable tool to easily and reliably attach longer, more difficult formulas. You can also use the Formula Builder to insert RAND. Note: in the newer versions of Excel, as you begin to type, you will be provided with a list of relevant functions to choose from: See? It’s practically a shortcut already. Because it’s such a short function, typing it manually is arguably the quickest, and a general rule of thumb is to learn the long-hand version first, thereby making you worthy of the shortcut. The most common random number generator (RNG) in Excel is the RAND function. Ultimately, macros will give you the most comprehensive power, and you can learn all about their amazing capabilities in this macro and VBA tutorial.
Once we have that down, we’ll write a simple macro to generate random numbers, too. The first thing we’ll look at is the RAND function and some of its variations. In Excel, there are several ways to generate random numbers depending on your requirements and skill level. Sometimes an unpredictable result is exactly what you need. Generating random numbers in Excel can be useful for a number of applications, from statistical sampling to computer simulation.
