How to Convert XML to CSV in Python 3

If you've ever found yourself faced with the task of converting an XML file into a CSV format using Python, you know that it can be quite a challenge, especially if you're dealing with large datasets. XML formatting is notoriously complex, and if not handled correctly, your output could end up empty or incorrect. Fortunately, in this post, we will walk you step-by-step through an effective method to convert XML to CSV using Python 3.

Understanding the Challenge

You might be asking yourself questions like:

Why is converting XML to CSV important?

What makes XML files difficult to read and convert?

XML (eXtensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. While its flexibility makes it a popular choice for data interchange, this flexibility also introduces complexity that can hinder conversion efforts.

Getting Started with Python

To convert XML to CSV in Python, we can utilize libraries that simplify the process. One of the most popular libraries for handling XML data is BeautifulSoup. This library allows us to easily parse XML files, while Python's built-in csv module will help us write our data to a CSV file.

Required Libraries

You'll need to install the BeautifulSoup library if you haven't already. You can do this via pip:
