Dame: identifying duplicate numbers within a column
Assume your invoice numbers are in column A:
In an empty ("helper") column put the following formula and copy down until the last invoice row. Change column to suit. =IF(COUNTIF(A:A,"=" &A1)1,"Duplicate","") Duplicate invoices will have "Duplicate" in the column. If invoice 123456 appears 3 times, each occurence will have "Duplicate" in your "helper" column HTH "Damondism's" wrote: I have a spreadsheet with thousands of invoice numbers, i need to identify duplicate numbers within a specific column.

After using Topper's suggestion, you can then work with just the duplicates
by using the autofilter (assumes you have a header row). Select the row with your headers, click Data/Filter/Autofilter. You should see a drop arrow next to the column w/Toppers formulae, click this arrow and select "Duplicate". Turn off the filter the same way you turned it on.
