Yes @NISHITHA We have LINQ which is very efficient & time saver as well, Let me know the input excel or Datatable you want to filter(remove duplicate) you can share a dummy table if data is confidential or a screenshot of input datatable is enough, I’ll help you out!

Hi @Ajay_Mishra

The Duplicate Rows are not based on Single Column



After Performing LINQ it would be

hello @NISHITHA ,

You can use this linq to remove the duplicates,

Out_Dt=(From row In in_DT.AsEnumerable() Select row).Distinct(DataRowComparer.Default).CopyToDataTable()

as you can see in below screenshot


I am attaching the .xmal file for your reference,

Remove duplicates.xaml (7.6 KB)

use this

dt.AsEnumerable.Distinct(system.Data.DataRowComparer.Default).where(Function(a) not a.ItemArray.All(Function(b) b.ToString.Equals(""))).CopyToDataTable

Hey @Shiva_Nikhil,

I think you didn’t got the question!

1st Table is Input and 2nd table is Ouput, and in your solution you are including both the tables as input. So, its not correct!

See my first post you have given the same solution

I have shared the output not the input.

In output 1 is Removing duplicates having empty row
In output2 is removing empty row as well
