All cells shud contain a unique ref how do i check 4 duplicates?
I am checking through a document register. The register relies on the fact
that every document has a unique referance number but i have come across a few duplicates. How do i check the rather large register for other duplicates without doing it manually, and without having a specific referance number to begin with. thanks |

You need a new column and assuming that the reference numbers are in column A
try in column b b2:=if(countif(a:a, a2)1,countif(a:a, a2),"") and then copy it down that will highlight duplicates and then you can do an auto filter on it to get them -- Hope this helps Martin Fishlock, Bangkok, Thailand Please do not forget to rate this reply.

Hi Charlie
An easy visual approach would be to use Conditional Formatting so that duplicates get highlighted in some easily visible colour (say Red or Green). Assuming your document ID numbers/file names are in col A then select the column and go FormatConditional Formatting. Change the first drop-down arrow to Formula Is and in the bar immediately adjacent to this, type the formula: =COUNTIF(A:A,A1)1 Then click the Format button and go to the Patterns tab and choose your desired colour. Click OK, and now you can scan down your list of files, and any duplicate cells will be highlighted in the colour you chose. Hope this helps!
