Excel Data Modeling: From Reporting to Strategic Architect

Stop just reporting the past and start designing the future. 🏗️ Most people use spreadsheets to describe what happened, but a true data architect builds engines that help make big decisions. In this video, we deconstruct the journey from raw data to professional forecasting models. We explore the "So What? Gap"—the chasm between numbers and strategy—and show you how to bridge it using tools like Pivot Tables and Black-Scholes financial engineering. You’ll learn why R-Square is often a lie and how the "Sieve of Truth" (Adjusted R-Square) protects you from the dangerous trap of overfitting. We also reveal the "Helper Cell" trick for interactive dashboards and how the LINEST function can become your secret weapon for legitimate, professional forecasts. It's time to give your dead data a voice. 🚀 Chapters: 00:00 – The Data Architect Mindset 00:42 – Bridging the "So What?"
