I want a single Excel workbook that turns my raw sales data into clear, actionable insight without requiring me to run complex formulas by hand. Using the latest AI-assisted features in Excel—Power Query, dynamic arrays, and, if helpful, embedded Python or VBA—I need the file to refresh automatically whenever I paste in new monthly figures and then serve up three layers of analysis: • Trend analysis that highlights seasonality, growth rates, and outliers • Predictive analysis that forecasts next-period revenue and unit demand • Customer segmentation that groups buyers by behaviour and value Interactive charts, slicers, and a concise dashboard should make the findings immediately readable for non-technical stakeholders. Please keep the workbook lightweight, clearly commented, and free of external dependencies so I can share it across the team. Acceptance criteria 1. Drop-in CSV of fresh sales data triggers every calculation and visual update with one click. 2. Forecast accuracy ±10 % against a held-out sample I will provide. 3. Segmentation logic documented on a separate sheet for future tweaking. 4. No macros disabled by default security settings. If you have experience pairing Excel with AI plugins or automating analysis through Office Scripts, that’s exactly what I’m after. Let me know the approach you’d take and the time you’ll need, and we can get started right away.
