Hi,

Is it possible to use an array formula on a range and have it report
the unique values in that range and the number of times each was
encountered?

Barring an array formula solution (preferred) I would entertain a
macro solution.

Thanks,

Eaxample: To get the unique entries in Col A and report then in Col B
and the number of times for each in Col C.
