You do realize that if you open Excel, it will also be opened on the Server, not the Client, and that there is no way you can force Excel to open on the client from the server?

I think you need to re-think your requirement before you start worrying about points 1-5, because if point 6 isn't going to work anyway, then there is no point in spending your time on the others...

Solution 4

Try this.
Export DataTable to Excel with Formatting in C#[^]

This might not answer all your points, but still you can derive from this.
