Your starter prompt

Help me analyse sales for [date range]. Columns: [column names]. Each row means [meaning]. Data: [paste a small anonymised sample or attach a supported file]. Identify missing values and explain how to calculate total sales, monthly trends and best-selling products. Show the formulas or calculation steps, state assumptions and never invent missing data.

Example inputs appear in square brackets; replace them with your own information.

What to do with the result

Compare totals with your original spreadsheet. Check currencies, refunds and date ranges. Save your formulas and charts in a new copy, not over the original.
