title: Counting Dublicates in Excel
body: <p>I have a column of names (200+) in one Excel-sheet. Some of the names are double. I would like to find out how many different names I have, so I need a function that counts identical entry's just once.
  Is it possible to write that in a formula? I don't want to use vba.
  I would be very happy if someone could give me a clue.
  Greetings!</p>
