NOTES

1. GIST does not allow Excel files. Convert the demo CSV file to Excel, or use your own dummy Excel file.
2. Run unpack.bat (Windows) unpack.sh (Linux/Mac). This will automatically:
   • Create a virtual environment - virtualenv venv
   • Activate the virtual environment - venv\scripts\activate (Windows) venv/bin/activate (Mac/Linux)
   • Install Flask pip install openpyxl
   • Run the example excel.py
