I having truble with deleting duplicate row in csv file

Could some one help me to delete duplicate row and append a each line of column with extra line

@Mugunthan

Use Read CSV file activity to read data from CSV file and will give output as dataTable. Then try this expression to delete duplicate rows.

dataTablename.defaultview.Totable(true,“ColumnName 1”,“ColumnName 2”,…).CopyToDataTable
