One can select the column header under which the duplicate values are to be analysed thereby restricting the search only to the columns which are not to be having any duplicates rather than the including the columns which would be having duplicates to serve a specific purpose.

Also, there might be data without any header row. They are also to be specified when the selected data is to be analysed for duplicates.

The header row checkbox is ticked by default. So, if the selected data does not have any, then it is the user who needs to uncheck this checkbox.

In this example, the header row checkbox is to be ticked since it has a header and all columns are also to be selected since the check for duplicates is to be carried out throughout. Click OK.
