Ugraded to Word 2013 Macro not performing

[Tye30]

Upgraded to Word 2013 from Word 2010 and the time to execute this macro went form 8 seconds to 208 seconds. When I run the code with not using

Application.ScreenUpdating = False

it actually runs faster at 191 seconds. Is there a setting I need to adjust or is this some kind of bug?

I am a beginner in VBA and I got this code from online

 
Dim StartTime As Double
Dim SecondsElapsed As Double
  StartTime = Timer
 
    Application.ScreenUpdating = False
 
    Dim oPara As Paragraph
    For Each oPara In ActiveDocument.Paragraphs
        If InStr(1, oPara.Range.Text, "!Z! !") = 0 Then
            oPara.Range.Delete
        End If
    Next
 
    With ActiveDocument.Range.Find
        .Replacement.ClearFormatting
        .Text = "!"
        .Replacement.Text = "|"
        .MatchWildcards = False
        .Execute Replace:=wdReplaceAll, Forward:=True, Wrap:=wdFindContinue
    End With
 
    Application.ScreenUpdating = True
 
  SecondsElapsed = Round(Timer - StartTime, 2)
  MsgBox "This code ran successfully in " & SecondsElapsed & " seconds", vbInformation

It's all relative and impossible to check without the document you are processing. On my PC (lots of memory and SSD drive) with a 20 page document it ran in just over a second, according to your timer, but it is also true to say that VBA processing in Word 2013/2016 is generally slower than it is in Word 2010

Thank you for replying Graham, and I have added an attachment of a modified version of the docs I use. I appreciate any help you may be able to give me!

Using your test document, which is far more complex than I had anticipated, the process is indeed much slower than in Word 2010 and even in 2010, your test document took rather longer than 8 seconds, however while my PC may have a lot of memory and a very fast drive, it does not have a particularly fast processor.

As you are processing a lot of paragraphs sequentially, there is not a lot you can do to speed that process.

If you can eliminate many (or all) of the unwanted paragraphs using the replace function then the process would have less to do and thus be faster. 'Replace' is infinitely faster than the paragraph looping.

e.g. a wildcard search for
\! \! \!*^13
replace with nothing will remove a lot of unwanted paragraphs very quickly and the processing time of your macro was then reduced to a third.

You should be able to remove many of the others similarly, but as the document is a mock up without real values, it is difficult to suggest the wildcard strings required, however see http://www.gmayor.com/replace_using_wildcards.htm
