How to Save an Excel Workbook to a Specific Directory with Openpyxl

One of the common challenges faced by Python beginners is saving files to specific directories, especially when using libraries like Openpyxl in combination with GUI elements from Tkinter. You may find yourself encountering an error like IsADirectoryError, leading you to wonder how to effectively save your Excel workbook to a location chosen by the user. In this post, we will walk through the issue and guide you on how to properly save your Excel files to a specified directory.

Understanding the Problem

When you're working on a Python project that involves creating Excel files using Openpyxl, you might want to give users the option to select where they want to save these files. This is typically done using a file dialog from Tkinter, allowing users to browse their file system for a suitable directory.

However, if you encounter an IsADirectoryError, it usually means that you’re trying to save the workbook without including the filename, which Openpyxl needs in order to create the file.

How to Properly Save to a Directory

To save a workbook to a specific directory in Python using Openpyxl and Tkinter, follow these steps:

Step 1: Setting Up Your Tkinter Interface

First, ensure that you have a Tkinter interface that allows the user to select a directory. Here’s a basic example of a button that will trigger the directory selection.
