Remove duplicate entries based on unique number Excel 2000

**IM22** · 04-09-2012, 07:23 AM

Hi,

I am adding entries to an existing file and need to remove any duplicates based on an index number which is unique for each item.

I know there's a function to do this in the new version of Excel but is there a way to do it in Excel 2000?

Hello IM22,

U can use contif function to count how many times the value is in list, so using a fill u can exclude the rows with 2 or more.

Cya,

Thanks for the reply, can you expand on it at all? I can't see how it would work, I tried it but the criteria seems to require that you state the value required which would mean I could only check for one number.

If your values are in A2:A100, in B2
=COUNTIF($A$2:A2,A2)>1 dragged down.
(replace comma with semicolon depending on regional settings)
This will give True or False. Then filter on True and delete those rows.
Does that help?

Hi

Another option, without filtering, is this(In B2 and copy down).

PHP Code:


=IF(MAX($B$1:$B1)=MAX($A:$A);"";SMALL($A:$A;1+COUNTIF($A:$A;"<="&N($B1))))

Hope, that helps you.

Edit: Change semi-colons, to comma, if you have to do it.
