Microsoft announced on October 9, 2026, that Copilot Notebooks would support editing Word, Excel, and PowerPoint files, along with collaborative reports and PDF creation. Microsoft describes these capabilities as a Frontier preview, its early-access program. Microsoft’s announcement
What Office editing in Copilot Notebooks includes
Users can view the files inline, edit them on the notebook canvas, or ask Copilot to change content and formatting. Microsoft’s examples include adding an introductory paragraph, bullet points, or a graph, and adjusting fonts, colors, or layouts. The examples show the kinds of changes Microsoft describes; they do not promise every feature available in the standalone Office apps.
The shift is in where the work happens: Office files can be handled inside a Notebook alongside project materials. Microsoft also says prompts can draw on notebook references or be expanded to “Work and web.” Separately, it lists Markdown, TXT, and RTF as generally available notebook reference formats.
Shared reports and PDFs
Teams can invite colleagues to refine the same file with Copilot. Microsoft also describes interactive reports that teams can create, edit live, and work on together, plus PDFs created from notebook content through chat. These are preview capabilities alongside the Office-file workflow.
Frontier access and rollout
For business users, Microsoft’s general Frontier guidance calls for a Microsoft 365 Copilot license and an organization enrolled in Frontier. Individual subscribers with Microsoft 365 Pro, Premium, Personal, or Family can opt in through supported web apps. Microsoft says access varies by feature, role, and subscription, so general eligibility for Frontier does not establish access to this specific Notebook feature on every plan. Microsoft’s Frontier guidance
Microsoft’s October 9 announcement uses two timing descriptions: its introduction says the update is coming to Frontier in the coming weeks, while the detailed feature section calls the capabilities currently available there. The announcement describes them as a Frontier preview, rather than a general-availability release.
