You could use a macro like the following. Just don't expect the processing to be instantaneous in a 1430-page document!
Code:
Sub ParseDoc()
Application.ScreenUpdating = False
Dim i As Long, RngSrc As Range, RngTgt As Range
With ActiveDocument.Range
For i = .Sentences.Count To 1 Step -1
Set RngSrc = .Sentences(i)
With RngSrc
Do While .Characters.Last Like "[ " & vbCr & Chr(160) & "]"
.End = .End - 1
If .Start = .End Then Exit Do
Loop
End With
If Len(RngSrc.Text) > 1 Then
Set RngTgt = RngSrc.Duplicate
With RngTgt
.InsertAfter Chr(11)
.Collapse wdCollapseEnd
.FormattedText = RngSrc.FormattedText
.InsertBefore "("
.Characters.Last.InsertBefore ")("
.InsertAfter ")" & Chr(11)
With .Find
.ClearFormatting
.Replacement.ClearFormatting
.Text = "[ ]{1,}"
.Replacement.Text = ") ("
.Forward = True
.Wrap = wdFindStop
.Format = False
.MatchWildcards = True
.Execute Replace:=wdReplaceAll
End With
End With
End If
Next
With .Find
.ClearFormatting
.Replacement.ClearFormatting
.Forward = True
.Wrap = wdFindContinue
.Format = False
.MatchWildcards = True
.Text = "^l^13"
.Replacement.Text = "^p"
.Execute Replace:=wdReplaceAll
.Text = "^l "
.Replacement.Text = "^l"
.Execute Replace:=wdReplaceAll
End With
End With
Application.ScreenUpdating = True
End Sub
