Extracting tabular data from PDFs made easy with Camelot. Extracting tables from PDFs doesn’t have to be hard.
Extracting tabular data from PDFs is hard. But what is even a bigger problem is that. A lot of open data is available as PDF files. This open data is crucial for analysis and getting vital insights. However, accessing such data becomes a challenge. For instance, let’s look at an important report released by the National Agricultural Statistics Service (NASS), which deals with the principal crops planted in the U.S:
For any sort of analysis, the starting point would be get the table with details and convert it to a format which can be ingested by most of the available tools. As you can see above a mere copy-paste in this case doesn’t work. Most of the times, the headers are not in correct place, some of the numbers are lost in tranisition and various other such problems.This makes PDFs somewhat tricky to handle and apparently, there is a reason for that. We’ll go over that, but let’s first try and understand the concept of a PDF file.
In the programming world, Data types play an important role. Each Variable is stored in different data types and responsible for various functions. Python had two different objects, and They are mutable and immutable objects.
We always say “Garbage in Garbage out” in data science. If you do not have a good quality and quantity of data, mostly likely you would not get much insights out of it.

Python Programming & Data Handling
There is an inordinate amount of data online that is available to be accessed. Knowing how to retrieve and analyze this data is an extremely useful skill to have. In this tutorial, we will use the python requests and Beautiful Soup libraries for quickly web scraping such data.
