When using RAND() or RANDBETWEEN() you’ll probably want to turn off Excel’s automatic recalculation or use Paste Special’s Values option to replace the function with its evaluated result. You’ll include the DATE() function to specify the bottom and top values as dates, using the form RANDBETWEEN(DATE( bottomdate),DATE( topdate)įor example, to return random dates between Januand January 30, 2012, you’d use the following function: =RANDBETWEEN(DATE(2012,1,1),DATE(2012,1,30))īeing random, resulting dates might repeat, but they’ll always fall within the specified dates. With just a little more work, you can use RANDBETWEEN() to generate random dates for a specific time period.

In Excel 2003, you must install the Analysis ToolPak add-in to access this function, as follows:
If you transpose the two arguments, the function will return an error. For instance, the function RANDBETWEEN(27,100) would return random values between 27 and 100. Where bottom is the lower value and top is the upper value. Fortunately, that’s unnecessary, thanks to RANDBETWEEN().Įxcel’s RANDBETWEEN() function returns a random integer number between two numbers, the function’s arguments, in the form RANDBETWEEN( bottom, top) It can be done, but it requires a convoluted formula that’s hard to remember. Return values that are either between or equal to This function will return values that are less than or equal to 0 and more than 10. Generating other types of random values, such as dates, isn’t. You will get a random number ranging from 0 to 1 if you use this formula. If you want random integers, you’d wrap the RAND() function in an INT() function.Īs just shown, generating random numbers between 0 and another number is relatively easy. RAND () is a volatile function, meaning that a new random number is generated every time the worksheet is calculated. It returns a random decimal number (real number) between 0 and 1. To generate a random number between 0 and 10, you’d multiply the results of RAND() by 10 to generate a random number between 0 and 100, you’d multiply by 100, and so on. The RAND function in Excel is one of the two functions specially designed for generating random numbers. This function doesn’t take an argument it just returns a random value between 0 and 1. Go to the Ablebits Tools tab > Utilities group, and click Randomize > Select Randomly: On the add-ins pane, choose what to. When you need a little more flexibility try RANDBETWEEN(). Generate random dates within a specific date rangeĮxcel's RAND() functions generate random values between 0 and 1.
