Microsoft is testing a COPILOT function in Excel that uses OpenAI's gpt-4.1-mini model to automatically fill spreadsheet cells through natural language prompts. The function can classify feedback, generate summaries, and create tables based on specified cell ranges. Microsoft warns against using the AI function for numerical calculations or scenarios involving legal, regulatory, and compliance implications because COPILOT "can give incorrect responses." The feature processes up to 100 functions every 10 minutes and cannot access information outside the spreadsheet.
