Let's explore two powerful ways to work with Excel files:

1. Python scripts using the openpyxl library;

2. Real-time interaction via the Excel MCP server.

Now let's build a dashboard directly inside that Excel file using openpyxl.

Then

This script adds a new sheet with analytics.

Everything is created automatically — no manual formatting required.
