Frequently Asked Questions

Why is Copilot in Excel not generating a forecast for my sales data?

Copilot requires data to be formatted specifically as an Excel Table. Select your data range and press Ctrl+T to convert it. Additionally, ensure your columns have distinct text headers and that there are no blank rows or merged cells disrupting the dataset.

What kind of data fields are best for an accurate sales forecast?

For accurate forecasts, your table should include consistent time-based fields (like Date, Month, or Quarter) and quantitative metrics (like Units Sold or Total Revenue). Categorical fields like Product Type or Region also help Copilot provide more segmented insights.

Can Copilot predict seasonal sales trends automatically?

Yes, if your historical dataset spans multiple years and demonstrates clear seasonal patterns, Copilot's algorithms can detect these recurring fluctuations and factor them into its future quarterly or monthly estimates.
