im struggling find answer this. want find duplicates in column b when column g not "n/a" using conditional format make column b red here example data server name(col b), nat (col g) myserver, n/a <---- should not checked myserver, n/a <---- should not checked myserver, 10.10.10.10 <----- should checked myserver, 10.20.20.20 <----- should checked myserver1, 1.1.1.1 <---- shouldnt checked myserver1, n/a <---- shouldnt checked obviously top 2x records shouldn't checked duplicates, next 2x records should checked dont n/a, last 2 records shouldnt checked there no duplicate (due 1 record having n/a) for reason when tried toms formula above wouldn't work conditional formatting rule, if amend (assuming g2 header): =and(countifs($b:$b,$b4,$g:$g,"<>n/a")>1,$g2<>"n/a") it should work, if have more 300 rows, excel slow, if create hidden column forumla , set conditional formula to: =$j=true
