Counting Unique Names

**BRodgers25** · 08-07-2012, 12:17 PM

I have a sheet where column A is a text list of names. Columns B-E is other data. Some of the names in A are duplicates. I need a count of the unique names in column A at the bottom of a range. Can anyone help with a formula?

Thanks for your help.

For count of unique value in A1:A10

=SUM(IF(FREQUENCY(MATCH(A1:A10,A1:A10,0),MATCH(A1:A10,A1:A10,0))>0,1))

confirmed with <Ctrl><Shift><Enter>

Thank you! Perfect. One more quick question: If I want to use this formula on a second range of cells in the same sheet, is there an easy way to copy and "paste special" to automatically pick up the second range? Or do I just type in the second range manually - which is really no big deal. Always trying to save keystrokes.

I am going to study the logic of this formula so I'll understand it better and can learn this stuff myself.

Thank you again.

Alternate non-array formula:

And I'm not sure what you mean by second range. You want to apply the formula to C10:C20 instead of A1:A10?

Thank you tigeravatar. The way I currently have it, I have calendar year 2010 in rows 2-57. Then have calendar year 2011 in rows 62-141 continuing down the same sheet. On the next tab I look at the same data, arranged similarly, by fiscal year.

You have all been very helpful.

Unfortunately a formula copy paste will only pick up a different range relative to the paste location from the copy location. So if you copy it from A1 and paste it to D3, the cell references will move right 3 and down 2. So you'll need to type in (or select) the different cell range if that type of copy/paste won't fit your needs.

Got it. Thank you very much.
