Try a Spreadsheet Task with a Known Answer
A small workbook is enough to check formula writing, data cleaning, and whether calculations survive editing. Create two tabs called Orders and Products. Add the following rows to Orders:
OrderID,Date,SKU,Region,Qty
O-01,2026-01-03,P01," North ",2
O-02,Jan 4 2026,P02,South,3
O-02,Jan 4 2026,P02,South,3
O-03,2026/01/05,P01,North,1Add this data to Products:
SKU,UnitPrice
P01,10
P02,25For an assistant that edits workbooks, use this prompt:
In Orders, remove duplicate OrderID values, trim the Region names, and make the dates consistent. Look up each SKU’s UnitPrice from Products. Add a Revenue column that multiplies Qty by the looked-up price. Create a Summary tab with total revenue by region. Keep the price lookups and revenue calculations as formulas.
The cleaned workbook has three orders. Revenue is 30 for North, 75 for South, and 105 overall. Change the price for P01 from 10 to 12. The total should recalculate to 111.
For a formula generator, request an Excel or Google Sheets formula that looks up the SKU in Orders!C2 against Products!A:B and returns the matching price. Paste the formula into your workbook and test it against P01 and P02.
