basic regex in Word macro

[gmaxey]

The macro worked fine here. What line generated the error?

.Text = "([0-9])([ ]{0,1})(l[!a-z])" results in an invalid pattern match. VBA can't find nothing [ ]{0,1} represent nothing

I'm not sure what you are really after, but if it is thins 6 l, 6 l or 6l = 6nbsl, 6nbsl and 6nbsl then try:

Dim oRng As Word.Range
  Set oRng = ActiveDocument.Range
  With oRng.Find
    .Text = "([0-9])([ ]{1,})(l[!a-z])"
    .Replacement.Text = "\1^s\3"
    .MatchWildcards = True
    .Execute Replace:=wdReplaceAll
  End With
  Set oRng = ActiveDocument.Range
  With oRng.Find
    .Text = "([0-9])(l[!a-z])"
    .Replacement.Text = "\1^s\2"
    .MatchWildcards = True
    .Execute Replace:=wdReplaceAll
  End With
End Sub
