Converting Complex Nested JSON to Excel or CSV Using Python
In today's data-driven world, working with JSON (JavaScript Object Notation) is a common task, especially when dealing with APIs or data exchanges. Sometimes, however, the format becomes too complex — particularly with nested schemas — and converting it into a more manageable form like an Excel spreadsheet or CSV can feel daunting. In this guide, we’ll outline a step-by-step approach to convert a complex nested JSON schema into a clean and organized Excel or CSV format using Python, specifically leveraging the powerful pandas library.
Understanding the Problem
Imagine you have a complex nested JSON structure that contains several data elements. Here’s a simplified version of what that could look like:

The goal here is to convert this JSON into a CSV format or Excel spreadsheet where:
All data elements are clearly listed.
Nested data elements are properly formatted to indicate their hierarchical relationship with parent elements.
For our example, the desired output format looks like this:
