Export PDF to editable word file

I need to edit a document created with Microsoft Word in " *docx "  form that I saved from Word as a PDF document. Now I want to return the document to the original  word format. That is easy enough using my Acrobat pro DC trial program. HOWEVER, it appears that in many pages the Blank areas or the spaces between words is filled with an exclamation symbol  ( ! ). Many, many of them. There are too many to sit and erase them all. In the PDF file the formatting is perfect. How do I easily correct this issue without completely redoing this 12 page document. Thank you Bill
