Provide column definitions, Excel version and three sample rows with expected results. Keep the test workbook disposable.
Environment and inputs: Copilot user guide · Feature and source access depend on the active account, app and organization settings. Optional file or app steps have a text-excerpt fallback. No fixed model version, price or usage quota is assumed.
What you will make
A practical Copilot guide to test a suggested Excel formula on boundary cases. Use the sample input and prompt, then check the result. Use a fictional Microsoft 365 workplace task as the practice setting. Identify the file or excerpt that supports the requested result.
Prepare the source and scope
Provide column definitions, Excel version and three sample rows with expected results. Keep the test workbook disposable. Open your available Microsoft Copilot experience and confirm whether it can read the intended work source.
Try this prompt
In Copilot, provide the prepared input, then send the following request. For real work, replace fictional details with approved facts.
Suggest a formula for overdue checks using the supplied due date and completion status. Explain behavior for blank dates and completed items.Review the result
Enter the formula in the test sheet and compare all expected outputs, including a blank due date. Record each correction and its supporting source.
If the answer is wrong or incomplete
A syntactically valid formula can implement the wrong rule. Resolve whether missing dates are overdue or unknown before rollout. If the active Copilot surface cannot access the file or app, paste an authorized excerpt into chat. Keep the same review criteria for the text-only workflow.
Practice and completion check
Repeat with one incomplete input. Check the answer against the review criteria, remove unsupported claims and save the prompt with its source version. This workflow has not been verified in a customer deployment.
