At least some of the issues you're having, especially with numbers, are because the code uses ".MatchWholeWord = True". Without this, there would be a significant risk that some of your other Find/Replace expressions would be updating parts of words. That may also explain why it doesn't work with "No-width optional break" text. I don't understand why you'd bother with rows 5-11, since the Find & Replace text is the same for each of them. For the remainder, you might use a separate worksheet and run a separate Find/Replace without the ".MatchWholeWord = True".

Thank you Paul.
Ok. The items within the lines 5 and 11 are not the same. Line 5 is to remove the white space at the end of a paragraph, and line 11 is to remove the white space between the opening parenthesis and the blank space before the closing parenthesis.

Another question: I often have to do Find & Replace only within the file that is opend, I would like to know how I could modify the code without saving the file and then go on to do Find & Replace?

Thanks
