If your PDF file is not secured with a password, then copying it into Microsoft Office Word is really easy.
  However, copying into Microsoft Word from a password-protected PDF file is not quite so simple.
First, I will explain how to copy to Microsoft Word from an Adobe Acrobat file that is not password-protected.
Obviously the first step is to open Adobe so that you can read your PDF file.
  Then choose the "Select All" option in the "Edit" menu (unless you wish to only copy part of the file, in which case you simply highlight the parts of the file that need to be copied into Word).
  Next click on the "Edit" menu and select the "Copy" option.
  On Microsoft Office Word, choose the "Paste" option from the "Edit" menu.
  And there you have it! Another way to do it is to save your file as a TXT document and then copy the contents of the TXT file and paste them into Word.
  The last step would be to edit the document if you need to.
If your PDF file is protected, you may not be able to copy the contents in this way.
  Unsure  about whether or not your file is protected?  Simply view the "File" dropdown menu, move your pointer to the "Document" option, hit the "Security" option and hit the option that says "Show Security Properties.
"  It will tell you if copying of the file is allowed or not.
  If it is not allowed, you can use a converter.
One converter you can use is a free PDF to TXT converter, which you can search for on Google.
  It will convert your PDF to a TXT file.
  Then, as described before, you can copy from the TXT file onto Word, although not everything may end up on the Word document exactly like the PDF file.
The best thing to use is a PDF to Word converter.
  It will copy everything directly to a Word document exactly the way it was on your PDF file.
