Microsoft has introduced a new AI-powered function called =COPILOT() in Excel, currently available in the Beta Channel. This feature allows users to input AI prompts directly into spreadsheet cells, enabling dynamic analysis, content generation, and brainstorming within the grid. The COPILOT function can categorize data, generate summaries, tags, tables, and more, with results that update automatically as the underlying data changes. Microsoft emphasizes that while the function enhances productivity by integrating AI with traditional Excel formulas, users should be cautious as it may produce incorrect responses in high-stakes scenarios. The rollout reflects Microsoft's ongoing efforts to embed AI capabilities across its Office suite, aiming to streamline data handling and decision-making processes for users.
