Am I missing the problem here?
Edit->Find
"Find What" -> '
If you record it as a macro you get ;
Cells.Find(What:="'", After:=ActiveCell, LookIn:=xlFormulas,
LookAt:= _
xlPart, SearchOrder:=xlByRows, SearchDirection:=xlNext,
MatchCase:=False) _
.Activate
Not if the apostrophe is the prefix character. To get around it use VBA:
Sub RemApos()
Dim rngArea As Range
For Each rngArea In ActiveSheet.Cells. _
SpecialCells(xlCellTypeConstants).Areas
rngArea.Value = rngArea.Value
Next
End Sub
