Check if A1 is blank, then set its value to anything you like, then run your Excel VBO/Get Worksheet as Collection Offset action.
It does stupid stuff like:
Dim cell as Object = ws.Range(Start_Cell)
Dim r as Object = ws.UsedRange.Offset(cell.row-1,cell.column-1)
r.Select()
r.Copy()
If your Start_Cell is A5, UsedRange is something like A5:Z100, after offset, actual range you are readding is A9:Z104
