Re: how to highlight duplicate text in columns?

["Andreas J. Guelzow" <aguelzow pyrshep ca>]

Let's say that A1:A10 is the region of interest.

Select A1 down to A10 so that A1 is the primary cell.
Then choose Format->Cells->Conditional Formatting
Click Edit Style and pick the Background Color Red, OK
Select as condition "_expression_ x evaluates to TRUE".
Enter as x: countif(A$1:A$10,A1)>1  and finish with tab
click "Add"
click "close"

Any cells with duplicate value in A1:A10 should now be highlighted in red.

I don't really know if the conditional format feature can do that, but you can use something like countif(A$1:A$10,A1) in another column to determine which cells are duplicates (i.e. count > 1).  Then you could use conditional formatting on the countif() column.

Hi all,

 

I'm thinking this would fall under conditional formatting, but have not been able to find the option i need in the program or manual. I need to search a single column containing some 12,000 rows of text and highlight any duplicates without removing anything. Any help much appreciated!

 

peace
