Convert Text to Numbers With VBA

If you frequently convert text to numbers, you can use a macro.
Add a button to an existing toolbar, and attach the macro to that button. Then, select the cells, and click the toolbar button.

Sub ConvertToNumbers() 
  Cells.SpecialCells(xlCellTypeLastCell) _
    .Offset(1, 1).Copy
  Selection.PasteSpecial Paste:=xlPasteValues, _
     Operation:=xlPasteSpecialOperationAdd
  With Selection
     .VerticalAlignment = xlTop
     .WrapText = False
  End With
  Selection.EntireColumn.AutoFit
End Sub
