A pivot table won't count unique values, but there's a workaround here,
if you're using an Excel list as the source:

I have data like this:

ABC BOX1
ABC BOX1
EFG BOX2
HIJ BOX3
KLM BOX4

And would like to use the Pivot Table to count the unique values in ColA:

BOX1 1
BOX2 1
BOX3 1
BOX4 1


For some reason, I am getting the following:

BOX1 2
BOX2 1
BOX3 1
BOX4 1

Thank you in advance.
