Hello All
I'm sure there is an easy fix for this but I'm banging my head against the wall trying to figure out what it is. I have data that occupies several columns. There are lines that are duplicated. I would like to either copy all duplicated lines to a different worksheet or use conditional formatting to highlight all duplicated lines. Any help would be greatly appreciated.

Thanks

Hi beerwOlf,

Add =SUMPRODUCT(($A$1:$A$100=content_colA)*($B$1:$B$100=content_colB)*1) to a new (hidden) column and copy it for all lines. This function works like a multiple COUNTIF().

Ones you made this column you can make a conditional format on either this new column or all cells in the row.

I don't think that is what I was looking for. Let me try top explain better. I have headers at the top of columns A thru Z. The rows (or records) are being filled by pulling data from a type of DB when I run the report. Somehow I am getting records that are duplicated. Instead of looking through every record to see if there are an duplications I would like to have conditional formatting seek them out for me and highlight them. Column A and D are the 2 columns that I need to compare off of. I can run the Advanced Filter option but that just hides the duplicates. I was to be able to see them and make notes as to which ones they are. I hope this is a better explanation.

Thanks

Hi:
If you can get your data into Microsoft Access (from Access, GET EXTERNAL DATA...) you can run a find duplicates query with the query wizard.

----------------------------------------------------------------------------------
Note: If you can change the query itself that you are basing your report on, you might be able to fix the problem by adding the keyword DISTINCT to the query statement:

SELECT DISTINCT table1.Field1, table2.Field2, etc....
rather than:
SELECT table1.Field1, table2.Field2, etc....

Hope this helps

I've got what you're probably looking for. The following TWO formulas entered in the conditonal formatting boxes look for duplicate lines in which both cell A# matches A## and D# matches D##. That was in case you might ever have the same item in column A with a different value in column D. The way I built this, I used the first condition to turn the cell green; this highlights the first occurance of an entry duplicated further down the sheet. The second condition I used to turn the cell red; indicating a duplicate entry's second or subsequent occurance.

Condition 1:
Code:
=IF(AND(COUNTIF($A$2:$A$100,$A2)>1,COUNTIF($D$2:$D$100,$D2)>1,COUNTIF($A$2:$A2,$A2)=1,COUNTIF($D$2:$D2,$D2)=1),1,0)

Condition 2:
Code:
=IF(AND(COUNTIF($A$2:$A$100,$A2)>1,COUNTIF($D$2:$D$100,$D2)>1),1,0)
