With the textboxes on a form you can use the Controls collection.
For Each oControl In Me.Controls
If Typename(oControl) = "TextBox" Then
iCellNumber = Val(Mid$(oControl.Name, 3)) 'Assumes all textboxes have two letter names
cells(iCellNumber ,1).Value = val(oControl.Text)
End If
Next oControl
If the controls are on the sheet, you can use the shapes collection on that sheet
For Each oControl In Me.Shapes
If InStr(oControl.Name, "TextBox") = 1 Then
iCellNumber = Val(Mid$(oControl.Name, 3))
cells(iCellNumber ,1).Value = val(oControl.Text)
End If
Next oControl
