Counting Names in a Column, Ignoring Duplicates
Is there a way to count names in a column but have the formula ignore
duplicates? example: Column A John Smith John Smith Jane Doe Joe Smith the formula would give me a total of - 3 I appreciate any and all help. Thank you in advance. |

=SUM(1/COUNTIF(A1:A10,A1:A10))
and confirm as an array formula (use CNTRL-SHFT-ENTER rather than just ENTER) will display 3 for your example. -- Gary''s Student gsnu200710 "Bruce" wrote: Is there a way to count names in a column but have the formula ignore duplicates? example: Column A John Smith John Smith Jane Doe Joe Smith the formula would give me a total of - 3 I appreciate any and all help.

This isn't working. When I enter the formula I get a "DIV/0" error.

That probably means there are empty cells within the range.
Try this (normally entered, not an array): =SUMPRODUCT((A1:A10<"")/COUNTIF(A1:A10,A1:A10&"")) Biff "Bruce" wrote in message ... This isn't working. When I enter the formula I get a "DIV/0" error.

Thank you for your reply. Your formula is counting the names but it's not
ignoring duplicate names. Any other suggestions? "T. Valko" wrote: That probably means there are empty cells within the range.

Biff:
Why is the &"" used (at the end) below? It still works without it (just experimenting here).. TIA, Jim May "T. Valko" wrote in message : That probably means there are empty cells within the range.

Try leaving some empty cells in A1:A10.

Dave,
Your right - causing a cell to go blank does result in #DIV/0! But I don't get how th &"" addition prevents it!! Jim " wrote in message : Try leaving some empty cells in A1:A10.

The &"" will make the empty cell look like a cell that had ="" in it--it won't
be empty--just a 0 length string. JMay wrote: Dave, Your right - causing a cell to go blank does result in #DIV/0! But I don't get how th &"" addition prevents it!!
