Function BreakCase(ByVal str As String) As String
  'moonexcel.com.ua
  Dim FCalc As Object
  
  FCalc = CreateUnoService("com.sun.star.sheet.FunctionAccess")
  
  str = Replace(str,"-"," ")
  str = Replace(str,"_"," ")  
  str = FCalc.callFunction("TRIM", Array(str))  
  str = FCalc.callFunction("REGEX", Array(str,"([:lower:])([:upper:])","$1 $2","g"))
  
  BreakCase = LCase(str)
