![]() The syntax of the RANDARRAY Function is as follows: =RANDARRAY(,) where: The RANDARRAY Function returns an array of numbers, within an interval that is specified. In our formula, we are utilizing the XLOOKUP and RANDARRAY dynamic array functions. These functions are only available to Office 365 users. In this formula, we are taking full advantage of dynamic array functionality.ĭynamic array functions allow you to work with multiple input values and also return multiple values into different cells. We have the same sample dataset we used above, showing the Helper Column, i.e., column A, a list of first names in column B and a list of last names in column C. In this example, we want to create a list of five random full names. We have already seen how to generate a random full name in our example above. Also read: How to Generate Random Letters in Excel? Generate a Random List of Names Using XLOOKUP, RANDARRAY, and the CONCATENATION Operator Note: This is the shortcut key for the Calculate Now feature. The first name and the last name are combined through our TEXTJOIN Function, with a space specified as the delimiter between them.Įvery time, we want to generate a new random full name, we simply press F9 on the keyboard. Our return_array, in this case, is column C. However, this time we want to select a matching last name from column C. Our second XLOOKUP Function follows a similar logic to that of the first one. This first XLOOKUP Function thus returns a random first name from Column B. Since our return_array is column B, the matching corresponding value is found in column B. In other words, we are telling the function to randomly pick a number from column A. Let’s just remind ourselves that our lookup_array in column A. So in our first XLOOKUP Function, we are letting the RANDBETWEEN Function select a random number between 1 and 50 as our lookup value. If -2 is specified, then the search is binary on descending sorted data. ![]() If 2 is used, then the search is binary on ascending sorted data. If -1 is specified, then the search is from last to first. If 1, which is the default, is specified, then the function searches from first to last. search_mode specifies the search mode you’d like to be used.This is an optional value, and 0 is the default. 2 allows one to perform a wildcard character match. 1 indicates an exact match or next larger. ![]() 1 indicates an exact match or next smaller. 0 indicates an exact match, and if no matches are found, #N/A is returned.
