Word has a keyboard shortcut to convert lowercase to uppercase. Shift + F3. Excel doesn’t. Macros to the rescue again.

The following macro will convert all letters in a cell or range to uppercase. It ignores any formulas in the range.

You first select the range and then run the macro.

Sub ConvertToUppercase()
' This macro converts all the letters in
' the selected cells to uppercase
' it ignores formula
 
Dim c As Range
 
If TypeName(Selection) <> "Range" Then Exit Sub
 
 For Each c In Selection
 
  If Not(c.HasFormula) Then
 
   c.Value = UCase(c.Value)
 
  End If
 
 Next c
Set c = Nothing
End Sub

If you need to convert to lowercase use the LCase command instead of UCase in the code.
