Hi @gantamohan502

dt1.AsEnumerable().GroupBy(Function(row) row("CityId")).Select(Function(group) group.First()).CopyToDataTable()

uniqueRows = (From row In dtInput.AsEnumerable()
                  Select row).Distinct(DataRowComparer.Default).CopyToDataTable()

In assign activity Try this linq query

Hii @gantamohan502

Try this query:

From row In DT_input
Group row By a = row("CityId").ToString.Trim Into grp = Group
Select grp.First
).CopyToDataTable

Hi @gantamohan502

You can achieve it by using the LINQ Expressions,
→ Use Read Range workbook activity to read the excel and store in a datatable called Input_dt.
→ Then insert the assign activity and give the below LINQ Expression,

- Assign -> Output_dt = Input_dt.AsEnumerable.GroupBy(Function(X) New With { Key .Column1 = X("CityId"), Key .Column2 = X("CityName") }).Select(Function(Y) Y.First).CopyToDataTable()

→ Then use the write range workbook activity to write the Output_dt to the excel.

By using LINQ Expressions also we can remove the duplicte rows in the excel.

Hope it helps!!
