Microsoft 365 caution regarding usage of COPILOT function in Excel:

See 'When NOT to use the COPILOT function'
https://support.microsoft.com/en-us/office/copilot-function-5849821b-755d-4030-a38b-9e20be0cbf62

"""
COPILOT uses AI and can give incorrect responses.

To ensure reliability and to use it responsibly, avoid using COPILOT for:

Numerical calculations: Use native Excel formulas (e.g., SUM, AVERAGE, IF) for any task requiring accuracy or reproducibility.

Responses that require context other than the ranges provided: The COPILOT function only has access to the prompt and context provided to or referenced by the function. It does not have access to other data from your workbook, data from other files or enterprise information.

Lookups based on data in your workbook: Use XLOOKUP to look up data based on a table or range.

Tasks with legal, regulatory or compliance implications: Avoid using AI-generated outputs for financial reporting, legal documents, or other high-stakes scenarios.

Recent or real-time data: The function is non-deterministic and may return different results on recalculation. Currently, the model's knowledge is limited to information before June 2024.
