By "in LabVIEW" do you mean you want to write code in LabVIEW to interpret the PDF and rewrite it as as Word document? While it could be done, you'd spend days trying to implement all the details of the PDF and Word formats, assuming you could get access to all the details.
Otherwise you'd be better off looking for an application with a command-line or ActiveX interface that you can run to do the conversion, and then call it from LabVIEW. Do you need all the content of the PDF, or just the text? If you only need the text, search this forum for "Text from PDF" and you'll find links to some VIs and tools that can do it. You can then use the ActiveX interface to Word to write that text into a Word document, but you'll lose all formatting and layout.
