Closing an Excel File and the Application: A Python Guide

If you’ve ever encountered the scenario where you close an Excel file through a Python script but find that the Excel application remains open, you're not alone. This issue can be frustrating, especially when you want to ensure that only the specific Excel application you've opened is closed, without affecting any other instances that might be running in the background.

In this guide, we'll explore how to effectively close both the Excel file and its corresponding application using Python. We'll provide a solution that employs the xlwings library to accomplish this task seamlessly.
