Generate a list of random numbers with no duplicates To bypass this limitation, use an advanced version of the formula described below. Please keep in mind that this simple formula creates a list of non repeating random numbers with a predefined step. The SORTBY function sorts the sequential numbers generated by SEQUENCE using an array of random numbers produced by RANDARRAY.This array goes to the by_array argument of SORTBY. The min and max value do not really matter, so we can leave these to defaults. The RANDARRAY function creates an array of random numbers of the same size as the sequence (5 rows, 1 column in our case).This sequence goes to the array argument of SORTBY. The SEQUENCE function creates an array of sequential numbers based on the specified or default start value and incrementing step size.Working from the inside out, here's what the formula does: If you'd like a different first number and increment, then set your own values for the 3 rd ( start) and 4 th ( step) arguments of the SEQUENCE function.įor instance, to start at 100 and increment by 10, use this formula: All other arguments are left to their default values, meaning the list will start at 1 and will be incremented by 1. In the above formula, you only define how many rows to fill.
