Didn't this ship sail in February 2013?
I do a fair amount of extracting content from PDFs (historical stuff, research, that sort of thing). I tried some "paid for" solutions which worked (sort-of) but didn't do the whole job. These days, I "copy and paste" into a very old text editor and work upwards from there. I doubt that method would please technical purists, but it gets large amounts of data out of old PDFs and into Excel spreadsheets with relative ease.
