Introduction

Being a high-level, interpreted language with a relatively easy syntax, Python is perfect even for those who don’t have prior programming experience. Popular Python libraries are well integrated and provide the solution to handle unstructured data sources like Pdf and could be used to make it more sensible and useful

PDF is one of the most important and widely used digital media. used to present and exchange documents. PDFs contain useful information, links and buttons, form fields, audio, video, and business logic.

Why Python for PDF processing

PDF processing comes under text analytics. Most of the Text Analytics Library or frameworks are designed in Python only. This gives leverage on text analytics. Once you extract the useful information from PDF you can easily use that data into any Machine Learning or Natural Language Processing Model.

Common Python Libraries

Here is the list of some Python Libraries could be used to handle PDF files

  1. PDFMiner is a tool for extracting information from PDF documents. Unlike other PDF-related tools, it focuses entirely on getting and analyzing text data.
  2. PyPDF2 is a pure-python PDF library capable of splitting, merging together, cropping, and transforming the pages of PDF files. It can also add custom data, viewing options, and passwords to PDF files. It can retrieve text and metadata from PDFs as well as merge entire files together.
  3. Tabula-py is a simple Python wrapper of tabula-java, which can read the table of PDF. You can read tables from PDF and convert into pandas’ DataFrame. tabula-py also enables you to convert a PDF file into CSV/TSV/JSON file.
  4. Slate is wrapper Implementation of PDFMiner
  5. PDFQuery is a light wrapper around pdfminer, lxml and pyquery. It’s designed to reliably extract data from sets of PDFs with as little code as possible.
  6. xpdf Python wrapper for xpdf (currently just the “pdftotext” utility)
