    Is it possible to copy the duplicates instead of removing them? What I’m trying to figure out is a way to find duplicates and copy them into a new worksheet. See example below:

    ActiveSheet.Range(“$A$1:$D$8”).CopyDuplicates Columns:=Array(1, 2), Header _

      Hi Jason,
      We do not have the built-in function to copy the duplicates, however we can write a userdefined function to do this. or we can use countif and advanced filter to get the duplicates.

    Dear Sir, To remove duplicate I found a code as below

    Selection.removeduplicates (1) Why is this (1) used when already the range has been specified to check for duplicate..
