Introduction

Have you ever found yourself needing to extract data from an Excel file into Python in a specific format? If your data is structured as a table with categories and items, converting that data into a Python dictionary can greatly simplify your data manipulation tasks. In this post, we’ll show you exactly how to extract Excel data using Pandas and obtain it in the desired dictionary format.

The Challenge

Imagine you have an Excel file containing data structured like this:
