How to Write Individual Items from a Dictionary to Separate JSON Files in Python

In the world of data handling, JSON (JavaScript Object Notation) files play a crucial role in storing and transmitting data. If you have a dictionary where each value is a list and you want to create individual JSON files for each item, you might find yourself facing a common programming challenge. Below, we’ll walk you through a straightforward solution using Python, specifically leveraging the powerful pandas library to simplify the process.

Understanding the Problem

Imagine you have the following dictionary:
