✍️ A Note from the Author

I built this course because I've spent too many late nights chasing down a single broken formula that ruined an entire month-end report. It's for the finance professional who knows that a spreadsheet is only as good as the trust people have in its numbers. I want to show you how to move past the fragile workbooks of the past by using the modern tools already sitting on your desktop.
