Try:
Code:
Sub DeleteStyleText()
Application.ScreenUpdating = False
Dim strStyles As String, i As Long
strStyles = strStyles & "Style1,Style2,Style3,Style4,Style5,"
strStyles = strStyles & "Style6,Style7,Style8,Style9,Style10,"
strStyles = strStyles & "Style11,Style12,Style13,Style14,Style15"
With ActiveDocument.Content.Find
.ClearFormatting
.Format = True
.Text = ""
.Replacement.Text = ""
.Wrap = wdFindContinue
For i = 0 To UBound(Split(strStyles, ","))
.Style = Split(strStyles, ",")(i)
.Execute Replace:=wdReplaceAll
Next i
End With
Application.ScreenUpdating = True
End Sub
where Style1 - Style15 are your actual Style names. You can use more Styles, or less; simply separate all the Style names with a comma.
