Adding XML Source to xlsx File in Python

If you're working with Microsoft Excel and have a template exported from Microsoft Dynamics NAV, you may encounter situations where you need to not only fill in the template but also add an XML source code file. This need arises when you want to ensure that your file maintains compatibility with the system you are uploading it to. In this guide, we will explore how to add XML source to an xlsx file using Python's xlsxwriter library.

Understanding the Challenge

As noted by Martin, who raised this question, the challenge lies in the fact that, while you can modify and fill the template using the xlsxwriter library, incorporating an XML source code file into the generated xlsx file is not straightforward. Many resources seem to overlook this specific use case, leading to frustration.

The Key Insight

One important point to understand is that an xlsx file is essentially a zip archive. This means you can manipulate it like a compressed folder, which opens up multiple pathways to add extra files, including XML sources.

Step-by-Step Solution

Here’s a comprehensive approach to successfully add an XML source to your xlsx file using Python:

Step 1: Create and Fill the xlsx File

Using the xlsxwriter library, create your xlsx file and fill it in as needed. Here's a simple example to get you started:

Step 2: Modify the XML Source Code

Before proceeding, ensure you have your desired XML source code ready. Modify it according to your needs so that it matches the format required for your application.

Step 3: Unzip the xlsx file

Since the xlsx file is a zip archive, you will need to unzip it. You can use Python's built-in zipfile module for this purpose.

Step 4: Add the XML File

Now that you have an unzipped folder representation of your xlsx file, simply copy your XML source code into the unzipped_example folder.

Place your modified XML file in the appropriate location within the unzipped structure.

Ensure it is named correctly and follows the structure that Excel expects.

Step 5: Repackage the xlsx File

After adding your XML source file, you now need to zip the folder back into an xlsx file.

Conclusion

By following these steps, you can seamlessly add XML source files to your xlsx documents created with Python's xlsxwriter library. This solution not only empowers you to maintain system compatibility but enhances your ability to work with Excel programmatically.
