How to Easily Write Multiple DataFrames to the Same Spreadsheet in Different Tabs with pandas

When you are working with data in Python, it’s common to use libraries like pandas to handle and manipulate dataframes. A frequently asked question among data analysts and developers is: How can I write multiple dataframes to the same spreadsheet and have each one on separate tabs? This need arises when handling multiple datasets that you'd like to present in a single, arranged spreadsheet file.

In this guide, we will walk through the steps to efficiently write multiple dataframes to different tabs in an Excel file while adding custom headers to each tab. Let’s dive into the solution!

The Problem

You have several dataframes containing important data (like ID numbers) that need to be presented in a user-friendly format. Each dataframe should reside on its own tab within a single Excel workbook, and you want to have a label or header at the top of each tab to provide context.

The Solution

With the help of the pandas library, you can achieve this easily using the ExcelWriter functionality. Below, we’ll break down the steps and the code needed to accomplish this.

Step 1: Import the Required Libraries

Start by ensuring you have pandas installed. If it’s not installed, use the following command:
