I just gave this a spin using the City of Santa Fe 2015 budget, a 150-pager. Seemed to be very fast in the conversion and quite accurate. Unless you need the text, it is even faster if you edit out text pages and just run those pages containing the desired tables. The result is that each page becomes a separate Excel page, then they can be sliced-and-diced as necessary.
Kudos to the ScraperWiki folks.
Accurately extract tables from PDFs
No more time consuming and error prone copying and pasting
