Counting unique text values across a range

[chendox]

This one has stumped me and can't find a solution on existing threads. I am trying to count the unique names (text) across a range of cells. Specifically, I have a scheduling table of Rooms (20 rooms) vs. Days (365 days). Whenever someone reserves a room, I put his/her name in the corresponding cell. Since a person can reserve multiple rooms on multiple days, I'm trying to get an accurate read of how many unique people are making reservations. Suggestions on how to approach would be greatly appreciated!

(I'm using Mac excel 2008, but can access a PC if I need to since I know features like Pivot Tables run differently)

Thanks. This seems to allow me to count uniques in a given row. How does it work across a range?

Sorry, I may have misunderstood your question (my bad)

Something like this? I think using COUNTIF would be suffice? If not please supply sample data along with expected result(s)

That's essentially the table format and I do want to know the count for each name. However, I first need to identify the unique names (A7:A11 in your example). [I have a table full of names that I didn't populate -- each individual entered their name themselves, so I don't know how many/who is participating to begin with]...

Ok I now understand, what your looking for is to extract a list of unique names from a range not just a column or row.

See if Aladins set up will assist you, sorry as need to rush of to a meeting. Hopefully this will help or someone else can jump in and help you out.

Hmmm... still don't see how I can use Autofilter, Advanced Filter, or the formulas to work across a range of columns and rows. Is there a way to combine all columns/rows into one column? (I have a 200 x 365 column x row matrix so it's not easy to copy and paste everything together)
