Winnie, you can use the upper function, with text in column, in another
column put =UPPER(A1) and copy down, you can then copy that column and paste
special back over you data.

Or you could use a macro like this


Sub MAKE_ALL_CAPS()
'select your range and run this to change to all CAPS
Dim cel As Range
For Each cel In Intersect(Selection, _
ActiveSheet.UsedRange)
cel.Formula = UCase$(cel.Formula)
Next
End Sub
