Learn how to Extract Tables in PDF using Camelot Library in Python

In this tutorial, you will learn how you can extract tables in PDF using camelot library in Python. Camelot is a Python library and a command-line tool that makes it easy for anyone to extract data tables trapped inside PDF files, check their official documentation and Github repository. Let’s dive in !

First, you need to install required dependencies for this library to work properly, and then you can install the library using the command line:

pip3 install camelot-py[cv]

Note that you need to make sure that you have Tkinter and ghostscript (which are the required dependencies) installed properly in your computer

Now that you have installed all requirements for this tutorial, open up a new Python file and follow along:

import camelot

# PDF file to extract tables from
file = "foo.pdf"

I have a PDF file in the current directory called “foo.pdf” which is a normal page that contains one table shown in the following image:

Table in PDF to extract in Python

Just a random table, let’s extract it in Python:

# extract all the tables in the PDF file
tables = camelot.read_pdf(file)

read_pdf() function extracts all tables in a PDF file, let’s print number of tables extracted:

# number of tables extracted
print("Total tables extracted:", tables.n)

This outputs:

Total tables extracted: 1 

Sure enough, it contains only one table, printing this table as a Pandas DataFrame:

# print the first table as Pandas DataFrame


              0            1                2                     3                  4                  5                 6

2        2012_2         3.30              1.3                  5.9%               9.5%              29.2%             17.4%
3        2145_1         0.68             11.2                  2.4%               0.1%               9.5%              2.7%
4        4234_1         0.59             58.7                  8.5%               1.3%               8.5%              3.3%
5        2032_2         0.17             57.8                 21.7%               0.3%               2.7%              1.2%
6        4171_1         0.07            173.9                 58.1%               1.6%               2.1%              0.5%

That’s precise, let’s export the table to a CSV file:

# export individually

Or if you want to export all tables in one go:

# or export all in a zip
tables.export("foo.csv", f="csv", compress=True)

f parameter indicates the file format, in this case “csv”. By setting compress parameter equals to True, this will create a ZIP file that contains all the tables in CSV format.

You can also export the tables to HTML format:

# export to HTML
tables.export("foo.html", f="html")

You can also export to other formats such as JSON and Excel.

It is worth to note that Camelot only works with text-based PDFs and not scanned documents. If you can click and drag to select text in your table in a PDF viewer, then it is a text-based PDF, so this will work on papers, books, documents and much more!

So this won’t convert image characters to digital text, if you wish so, I have a tutorial that uses OCR techniques to convert image optical characters to actual text that can be manipulated in Python.

Alright, this is it for this tutorial, check their official documentation for a more information.

How to extract tables from PDF using Python Pandas and tabula-py

A quick and ready script to extract repetitive tables from PDF

This tutorial is an improvement of my previous post, where I extracted multiple tables without Python pandas. In this tutorial, I will use the same PDF file, as that used in my previous post, with the difference that I manipulate the extracted tables with Python pandas.

The code of this tutorial can be downloaded from my Github repository.

Almost all the pages of the analysed PDF file have the following structure:

Image by Author

In the top-right part of the page, there is the name of the Italian region, while in the bottom-right part of the page there is a table.

Image by Author

I want to extract both the region names and the tables for all the pages. I need to extract the bounding box for both the tables. The full procedure to measure margins is illustrated in my previous post, section Define margins.

This script implements the following steps:

  • define the bounding box, which is represented through a list with the following shape: [top,left,bottom,width]. Data within the bounding box are expressed in cm. They must be converted to PDF points, since tabula-py requires them in this format. We set the conversion factor fc = 28.28.
  • extract data using the read_pdf() function
  • save data to a pandas dataframe.

In this example, we scan the pdf twice: firstly to extract the regions names, secondly, to extract tables. Thus we need to define two bounding boxes.
