Fuel Rebate Calculator

I wrote this tool to stop doing the same boring Excel work over and over every month. We had to process huge fuel reports manually to figure out rebates, so I built this to handle the math for me.

Built with:

• Python, OpenPyXL and CustomTkinter

How to use:

1. Install the libraries: pip install openpyxl customtkinter
2. Run the script and select your raw Excel file.
3. Hit "Export" and you're done.
