[excel] How to change Format of a Cell to Text using VBA

One point: you have to set NumberFormat property BEFORE loading the value into the cell.

Setting the property before loading the value made the number appear as I wanted, as straight text.

Could you try an autofit first:

Excel_Obj.Columns("A:V").EntireColumn.AutoFit
