Riley Brown tests Claude Opus 5 through the Excel add-in, starting with a financial-model example and then demonstrating setup, account connection and a short web-research prompt. The walkthrough focuses on operating directly inside a workbook, retaining formulas, selection context and organized sheet structure.
A fictional software business provides the main scenario-planning exercise. Brown requests a dynamic operating model with bear, base and bull cases, linked assumptions, sensitivity analysis, dashboards and reconciliation checks. He changes scenario selections and asks for additional comparison charts, showing how the outputs respond.
A second exercise compares cities using sourced data and user-adjustable weights, while another researches public companies. One Fable run stops without completing, after which Brown tests ChatGPT's add-in and then asks Claude to improve the resulting presentation. The video makes the failed run visible rather than treating every attempt as successful.
Brown prefers Claude's formatting and dashboard readability in these examples, but this is a hands-on demonstration, not an audited financial model or a universal benchmark. Generated formulas, factual research and investment-related conclusions still need human verification. The sponsor segment is excluded from the editorial account.
