Well, obviously, you'd only use the process I outlined for the ranges that should be converted to tables, not to the whole document. For a macro, you might try something like:
Code:
Sub Demo()
Application.ScreenUpdating = False
With ActiveDocument.Range
With .Find
.ClearFormatting
.Replacement.ClearFormatting
.Text = "?"
.Replacement.Text = ""
.Forward = True
.Wrap = wdFindStop
.Format = False
.MatchCase = False
.MatchWholeWord = False
.MatchWildcards = False
.MatchSoundsLike = False
.MatchAllWordForms = False
.Execute
End With
Do While .Find.Found
.Paragraphs.First.Range.ConvertToTable Separator:="?", AutoFit:=True, _
Format:=wdTableFormatList3, AutoFitBehavior:=wdAutoFitContent
.Collapse wdCollapseEnd
.Find.Execute
Loop
End With
Application.ScreenUpdating = True
End Sub
