![]() ![]() More interesting are the small breakouts on subsequent pages e.g.FY2017 Proposed Budget-Lowell-MA (Lowell).PyPDF2 Parsing result: this data parses out.Tabular data begins on page 15-16 (labelled 15-16).2016-budget-highlights.pdf (Seattle city budget summary).SCARY: some financial tables are split across two pages.PyPDF2 Parsing result: None of the tabular data is exported.Tabular data begins on page 30 (labelled ).2015-16-prelim-doc-web.pdf (Bellingham city budget).PDF examples I tried parsing, to evaluate the packages Does text always appear in the same place on the page, or different every page/document?.Vector images, charts, graphs, other image formats.FANTASTIC writeup of the low-level grind in extracting tabular data from PDFs that weren’t designed for ease of reuse:.Includes PDFInfo which does a great job of exporting metadata.requires no explicit knowledge of internal layout complexities) Orients to JQuery or XPath syntax (I.e.Wrapper around PDFMiner for ease of use.Python 2 (pdfminer3k, pdfminer.six apparently support Python 3).Great writeup of the trials of wrangling PDF document internal structures.The decision is often based on what acroread and okular do with the PDFs if they can display them properly, then eventually pdfrw should, too, if it is not too difficult or costly.” “There are a lot of incorrectly formatted PDFs floating around support for these is added in some cases.Multiple references to reportlab (complementary functionality).Heavily oriented to a printing workflow: manipulating paging, sizing, embedded images.Others suggested by Ed Borasky: ijmbarr/parsing-pdfs, reesepathak/pdf-mining.One StackOverflow comparison: : PyPDF2, PDFMiner, ReportLab.A more involved tutorial examining many packages: : Pdfrw, slate, PDFQuery, PDFMiner, PyPDF2.The strongest possible recommendation based on this research is GET AS MUCH OF THE DATA FROM DIGITAL SOURCES AS YOU CAN. The amount of work it takes code to parse structured data from analog input PDFs is a significant hurdle, not to be underestimated ( this blog post was the single most awe-inspiring find I made). These are neither conclusive nor comprehensive, but they are directionally relevant. These are the preliminary research notes I made for myself a while ago that I am now publishing for reference by other project members. ![]() I’m part of a project that has a need to import tabular data into a structured database, from PDF files that are based on digital or analog inputs. ![]()
