In most cases, you can use the included command-line scripts to extract text and images ( pdf2txt.py) or find objects and their coordinates ( dumppdf.py). The PDFMiner library excels at extracting data and coordinates from a PDF. If none of the Python solutions described here fit your situation, see the section for more information. There are other Python projects for creating PDFs, and several non-Python tools available for manipulating PDFs. This article focuses on extracting information with PDFMiner and manipulating PDFs with PyPDF2.

Includes sample code and command line interface, documentation. Includes sample code and command line interface Google group and documentation. Extracting text, images, object coordinates, metadata from PDF files. Requires PDFMiner, pyquery and lxml libraries. PDF scraping with Jquery or XPath syntax. Includes documentation on GitHub and PyPI. Simplifies extracting text from PDF files. Check out this tutorial by pdfrw’s creator, which mirrors the examples in this article. Pdfrw: Read and write PDF files watermarking, copying images from one PDF to another. The following list displays some of the most popular ones, although undoubtedly I’ve omitted some tools. There are several Python packages that can help. If you cannot get access to the information further upstream, this tutorial will show you some of the ways you can get inside the PDF using Python.
Chances are, now that it’s inside the PDF, it’s just a bunch of lines and numbers with no connection to its former structure of cells, formats, and headings. If you want to scrape that spreadsheet data in a PDF, see if you can get access to it before it became part of the PDF. Well, don’t do it if there is any way you can get access to the information further upstream. Still, the best advice if you have to extract or add information to a PDF is: don’t do it. Well, we are programmers too, and we are a creative bunch, so we’ll see how we can get at those internals. That means that in the end, a beautiful PDF document is really meant to be read and its internals are not to be messed with. The PDF reference specification (ISO 32000-1) provides rules, but it’s programmers who follow them, and they, like all programmers, are a creative bunch. Inside, they might have any number of structures that are difficult to understand and exasperating to get at.
#Python pdf reader skin#
PDF documents are beautiful things, but that beauty is often only skin deep.
