Microsoft Copilot Wave 2: Agents, Python in Excel, and Copilot Pages

Microsoft's Copilot Wave 2 update, rolling out from October 2025 through March 2026, introduced Copilot Pages (collaborative AI-generated documents), Python integration in Excel, Copilot Agents (custom autonomous assistants), and Sales Agent for automating SDR functions at scale.

The update deeply embedded AI into Excel, PowerPoint, and Teams, along with Copilot Tuning for fine-tuning models on specific organizational data. This is Microsoft's biggest AI integration step.
