Count formula

[kirstypie]

Hi there,

I have a worksheet that has a bunch of duplicates and I want to get rid of all duplication. I used this formula to determine which entries are duplicates: =COUNTIF(A:A,A1)>1 That gives me a true/false statement.

I know there is another variation of the formula that will tell you if the entry is the second (or more) occurrance, then you can sort and just delete all the extra entries without worring about losing the original. But I can't remember what that formula is. Any suggestions?

try this
=countif($a$1:a1,a1)

then copy that down, then where ever the number is greater than 1 is a duplicate.

Insert a row before the top row...

B2, copied down:

=ISNUMBER(MATCH(A2,$A$1:A1,0))+0

AutoFilter column B on 1 and delete all rows with 1.
