Converting Nested JSON Objects to a Pandas DataFrame: A Step-by-Step Guide

Working with JSON data is common in data analysis, especially when that data comes with nested structures such as arrays. This post will provide you with the essentials on how to convert a nested JSON object into a well-structured Pandas DataFrame, making analysis easier and your data more accessible.

The Problem

You may encounter scenarios where you need to deal with a JSON file containing nested fields. For instance, consider the following JSON structure:

Your task is to convert this nested structure into a DataFrame where each item in the intervalMetaData array becomes a separate column filled with corresponding values from intervalData.

The Solution

Let's break down the solution into clear steps to achieve this with Python’s Pandas library.

Step 1: Import Pandas and Create Your Data

Start by importing the Pandas library and defining your data.
