Marking Duplicates
I have a large spreadsheet(7000 entries) that I would like to mark any of the
row that are duplicates. In order to match the duplicates columns A B C have to be the same. I have attempted to use the following but it does not seem to work: =IF(COUNTIF(A:C,A2)1,"Duplicate","") I place this in column D then copy it down through the spreadsheet. Thanks for your help. |

Hopefully someone has a faster method, but this formula: =SUM(--((A1&" "&B1&" "&C1)=($A$1:$A$7000&" "&$B$1:$B$7000&" "&$C$1:$C$7000))) array-entered (That means hold down <ctrl<shift while hitting <enter) and copied down to row 7000 will return a count of the number of times A, B, and C are found in the table. It runs fairly slowly, though. --ron |
