In this episode of The ModSquad on Financial Modeler's Corner, Paul Barnhurst, Ian Schnoor, and Giles Male explore Microsoft’s newly released Excel Agent, a beta tool designed to bring AI into Excel Online. The team compares its performance to Rosie AI, running both through a range of tasks, including formula building, audit reviews, and a full five-year model forecast. Along the way, they test the tools against real modeling challenges like the Excel Esports case and a creative custom case, "The Humble MVP." This isn’t just about flashy tech. It’s a deeper conversation on where AI can help, where it falls short, and why core financial modeling skills still matter.

Expect to Learn

• What happened when Excel Agent tried to build a full five-year forecast model.
• Why solid modeling skills still beat "one-click" AI hype.
• Where AI tools succeed, and fail, in reviewing formulas and detecting issues.
• Why you should never fully trust AI without understanding what it’s doing.

• “Building a model is like flying a plane; you don’t want a rookie in charge when something breaks.” - Ian Schnoor
• “You can’t hit a prompt, go get a coffee, and expect a working model.” - Giles Male
