otherthan that we have any method it is just adding a column to an excel by using write cell activity with a series of numbers

Using For each datatable --> auto increment value and assign it to row/column index.
Iteration will be more here instead.

thing is i got the output but instead
1
2
3
4
5
i got as
0
1
2
3
4
5

it should start from 1 not from 0

Change the assign with: ((From dr As DataRow In dtData Where (Convert.ToInt32(dr(“ID”))+1) = id Select Convert.ToString(dr(“Role”))).ToArray()) and the id will start from 1
