I’m a contractor. One of my gigs involved writing parsers for 20-something different kinds of pdf bank statements. It’s a dark art. Once you’ve done it 20 times it becomes a lot easier. Now we simply POST a pdf to my service and it gets parsed and the data it contains gets chucked into a database. You can go extremely far with naive parsers. That is, regex combined with positionally-aware fixed-length formatting rules. I’m available for hire re. structured extraction from PDFs. I’ve also got a few OCR tricks up my sleeve (eg for when OCR thinks 0 and 6 are the same)
