There is free software that can be used to extract text from PDFs with some of formatting intact, but again, don't expect perfect results. See, e.g., calibre (which can convert to RTF format), pdftohtml/pdfreflow or the AbiWord word processor (with all import/export plugins enabled). There's also a PDF import plugin for OpenOffice.
Another option is to download and start using the free pdf viewer, Foxit (its good).Then you can 'Save As' and choose .txt to convert it to a text file.That will preserve all the formatting. Dunno whether you can do the same in Adobe because I stopped using it a while ago when I converted to Foxit.
Here is a free suite of office productivity tools that includes the ability to edit and export files in the PDF format. It is open-source software that provides users with a comprehensive set of applications including word-processing, spreadsheets, drawing, and presentation tools. 2b1af7f3a8
