By "upper and lower" I assume you mean Proper Case.

By formula enter =PROPER(cellref) in a hellper cell and copy down or across.

When happy, select these cells and Copy then Paste SpecialValuesOKEsc.

Delete original cells.

By macro...........


Sub Proper_Case()
'David McRitchie, programming, 2003-03-07
Dim rng1 As Range, rng2 As Range, bigrange As Range
Dim Cell As Range
Application.ScreenUpdating = False
Application.Calculation = xlCalculationManual
On Error Resume Next
Set rng1 = Intersect(Selection, _
Selection.SpecialCells(xlCellTypeConstants))
Set rng2 = Intersect(Selection, _
Selection.SpecialCells(xlCellTypeFormulas))
On Error GoTo 0
If rng1 Is Nothing Then
Set bigrange = rng2
ElseIf rng2 Is Nothing Then
Set bigrange = rng1
Else
Set bigrange = Union(rng1, rng2)
End If
If bigrange Is Nothing Then
MsgBox "All cells in range are EMPTY"
GoTo done
End If
For Each Cell In bigrange
Cell.Formula = Application.Proper(Cell.Formula)
Next Cell
done:
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
End Sub

Since you're not familiar with VBA and macros, see David McRitchie's site for
more on "getting started".

In the meantime..........

First...create a backup copy of your original workbook.

To create a General Module, hit ALT + F11 to open the Visual Basic Editor.

Hit CRTL + r to open Project Explorer.

Find your workbook/project and select it.

Right-click and InsertModule. Paste the code in there. Save the
workbook and hit ALT + Q to return to your workbook.

Run or edit the macro by going to ToolMacroMacros.

You can also assign this macro to a button or a shortcut key combo.
