Updated June 16, 2026: We have updated the timeline. Thank you for your patience. Introduction Copilot Notebooks enables users to generate Excel spreadsheets directly from the content and references collected in a notebook. Copilot creates a structured spreadsheet based on the notebook’s context, which can then be opened and edited in Excel. This capability streamlines the transition from ideas and source material into a usable spreadsheet by reducing manual setup and formatting. When this will happen: Public Preview via Frontier: Rollout begins in late March 2026 and is expected to complete by late April 2026. General Availability (Worldwide): Rollout begins in early June 2026 (previously late May) and is expected to complete by mid-June 2026 (previously early June). How this affects your organization: Who is affected: Users with access to Microsoft Copilot and Copilot Notebooks Organizations using Excel in Microsoft 365 A Microsoft 365 Copilot (Premium) license is required to use this feature What will happen: Users will be able to generate an Excel spreadsheet from content and references stored in a Copilot Notebook. The generated spreadsheet opens in Excel and can be edited like any other Excel file. The feature is enabled by default for eligible users. Existing Microsoft 365 security, compliance, and Copilot policies are respected. What you can do to prepare: No admin action is required.

Copilot processes existing content and references stored in a Copilot Notebook to generate a structured Excel spreadsheet. This processing occurs within Microsoft 365 services and respects existing security, compliance, and data residency boundaries. Does the change introduce or significantly modify AI/ML capabilities that interact with customer data? This change introduces a Copilot capability that uses generative AI to analyze notebook content and create an Excel spreadsheet based on that context. Does the change provide end users any new way of interacting with generative AI? Users can instruct Copilot to generate Excel spreadsheets directly from Copilot Notebook content, representing a new generative AI–assisted interaction within Microsoft 365.
