Building up 16 teams (2 persons per team) 12 times using excel

Hello,

I am preparing for a tournament and I am trying to build it up through Excel, the inputs of the tournament are as follow:

1- 32 players
2- 16 teams (each team consist of 2 players)
3- 12 Rounds (1 Round per day, which means there is 8 matches per day - every team is competing with another team)
4- Teams changes every round (which means two players can only meet once in one team for the 12 rounds, for example, in Round 1 player X is playing in the same team with player Y, however; in round 2 player X & player Y shouldn't be in the same team again everyone should team up with another players. This scenario keep on going until the rounds finish - each round different teams).

I have tried using this formula: {=index(array:list of the 32 players, mrand()+1) (I had to install the Morefunc add-in for the mrand() ) this gives me only the first round teams. However; for the second, third, forth,...... round I need to make sure that no one is playing again with the same player that he teamed with before. I don't want to manually check it, I need to make sure that excel is generating 16 teams every round different from the round before. Can excel do that?

Any Ideas? PLEASE HELPPPP

Thank you for helping in advance,

Yup, to clarify it more, for instance you will team up with John today (round 1), tomorrow round 2 you can team up with anyone in the 32 players list excluding John .

It could be something like the attached as a simple example of what I am trying to do.

As I said before generating the first 16 teams for the first round is not the problem, the problem is making sure that excel will not duplicate any team again for the remaining 11 rounds after round 1.

No worries mate, take your time and thank you in advance.

Cool mate anytime before Sunday afternoon is great, I'll be waiting for your solution and in the meantime I'll try to find a solution as well and I'll update you. Thanks again.
