I've converted a lot of PDF files into word by cutting and pasting:
1) In Adobe Acrobat, set the view mode to "continous" (very important)
2) With the text select tool, drag the mouse to highlight the entire PDF.
3) Paste into Word.
This process will preserve basic formatting of the text (bold, italic, fonts, etc...). Is this what you want to do, or am I missing something?
