Filtering repeating values in excel join datatable

Thank you @ppr
but at present when I am processing the attached file
join - Copy.xlsx (9.8 KB)

it is not returning any rows whereas expected was to skip the 2nd duplicate row

Please let me know if I am missing anything. Also it should return the same datatable incase there is no match - for below files -

join.xlsx (9.8 KB)
join_01.xlsx (9.8 KB)

Regards,
