# User Wants Python in Excel on a Toolbar: Self-Hosting an Automated Solution on a Friday (Infrastructure, DevOps, and Open-Source)

Welcome to this practical guide where we will show you how to seamlessly integrate Python scripts into Microsoft Excel’s toolbar for self-hosted automation. This tutorial is targeted towards experienced sysadmins and DevOps engineers who wish to enhance their homelab infrastructure with powerful automation tools.

Prerequisites

1. Install the latest version of Docker CE (5.0.8 or higher) on your system.
2. Ensure you have Docker Compose installed as well, version 1.27.4 or later is recommended.
3. Install the Python package management tool pip if it’s not already installed on your system.

Solution Breakdown

1. Create a new directory for this project and navigate to it in your terminal:

    mkdir pyexcel-toolbar && cd pyexcel-toolbar
   

2. Create a Dockerfile: This file will define the environment for our Python application.

    touch Dockerfile
   

3. Edit the Dockerfile to include the following content:

    FROM python:3.8-slim-buster
   
    # Install Python dependencies
    RUN pip install --upgrade pip
    RUN pip install openpyxl
   
    # Copy application code
    COPY . /app
   
    # Set the current directory to the app directory
    WORKDIR /app
   
    # Define the command to run when the container starts
    CMD ["python", "main.py"]
   

4. Create a new file named docker-compose.yml: This file will configure our Docker application.

    touch docker-compose.yml
   

5. Edit the docker-compose.yml to include the following content:

    version: '3'
    services:
      app:
        build: .
        ports:
          - "8080:8080"
   

6. Create a Python script (e.g., main.py): This file will contain the logic for your Excel toolbar add-in.

    touch main.py
   

7. Edit the main.py to include the necessary code for your specific use case.

8. Build and run the Docker container:

    docker-compose up --build
   

9. Access the application on your web browser: Navigate to http://localhost:8080 in your preferred browser to see your Python script running within Excel’s toolbar!

Troubleshooting

• If you encounter issues during the build process, verify that Docker and Docker Compose are correctly installed on your system.
• Ensure that your Python version is compatible with the dependencies specified in the Dockerfile.

Conclusion

In this guide, we’ve shown you how to create a self-hosted solution for integrating Python scripts into Excel’s toolbar using Docker and Docker Compose. This setup allows you to easily automate tasks while leveraging the power of open-source tools within your homelab infrastructure.

Security Considerations: Keep in mind that exposing the application directly to the internet can pose potential security risks. Always ensure proper firewall configurations are in place and only expose the service when necessary.

Performance Optimization: For better performance, consider using a cached Python environment and optimizing your Python code for specific use cases.

Common Pitfalls: Be cautious of memory leaks or resource exhaustion when working with large datasets or long-running tasks within the containerized environment. Monitoring resources closely is essential to avoid unexpected issues.
