Yes, there is a way. First, you insert a new column next to the column you want to randomize. Then, you populate your helper column with random numbers by using the RAND() function. After that, you sort the column with random numbers, and then select the required number of cells. If your knowledge of Excel formulas is above average, you can combine a few different functions together to select a random sample without duplicates. The downside of this approach is that new random numbers are generated with every recalculation of your worksheet, causing your random sorting and selection to change.
Our add-in lets you shuffle your data and select randomly exactly the way you want, without messing around with volatile Excel functions.
