    Random Groups w/No Repeats

    Good Evening!

    I have a classroom that has a max of 12 students in it. Every 5 weeks the class size fluctuates, so it's not always a static 12 students. I am trying to figure out how to create a spreadsheet in Excel that can organize the partners so that there are no repeats until all the pairing options have been exhausted.

    I found a great video online, only to find out that it MRAND doesn't work with my Office version (2016). (It's here if you would like to see what I have found thus far: youtube.com/watch?v=rYrGF8ib7WY)

    I've been trying to come up with a way to do this in Excel for well over a year and can't figure it out.

    Thank you so much for your help!

    Re: Random Groups w/No Repeats

    Here's how you do a random selection of a list without repeating without using MoreFunc (MRAND).
    Not sure how you'd do partners not repeating.

    The below simply picks a random person from the 12 without repeating, output in column C

    Random list, no duplicates
    A1:A12 Put a list of their names
    B1:B12 =RAND()
    C1:C12 =INDEX(A$1:A$12,MATCH(SMALL(B$1:B$12,ROW()),B$1:B$12,0))

    Ensure you describe your problem clearly, I have little time available to solve these problems and do not appreciate numerous changes to them.

    Anyone else have any suggestions? This is close but doesn't solve the problem. Thanks in advance!

    You could thank the person that made the suggestion and explain why it doesn't suit your requirement, rather than ask someone else to make a random guess as to what you actually want.
