Microsoft CEO Satya Nadella shows how Copilot can make you better at Word, Excel, and more using Vibe working

Microsoft CEO Satya Nadella has introduced a new era of productivity within Microsoft 365 by unveiling Agent Mode in Copilot. In a recent thread on X, Nadella demonstrated how this feature can manage multi-step workflows across apps like Word, Excel, and PowerPoint, turning everyday tasks into seamless, AI-powered processes.

Transforming ideas into documents and presentations
One of the key examples Nadella shared was how Agent Mode can take a short prompt and expand it into a polished PowerPoint presentation or Word document. Users can simply type an instruction such as, “create a presentation about the evolution of remote work,” and Copilot responds by pulling together research, drafting content, generating visuals, and even suggesting layout designs. Within the same conversational interface, users can select design themes, adjust the tone, or highlight specific focus areas without leaving the app. This turns what might normally take hours of work into a guided, collaborative process.

Excel: making data analysis accessible
Nadella also demonstrated how Excel users benefit from Agent Mode’s ability to perform data analysis without complex formulas. Instead of manually entering functions, a user can ask Copilot to “analyze sales performance and visualize trends.” The agent then checks the dataset, performs necessary calculations, fixes potential issues, and creates relevant charts such as line or bar graphs. Alongside the results, Copilot provides notes on the analytical steps taken, making the process transparent while surfacing actionable insights like top products, average margins, or growth patterns.

Word: seamless editing and refinement
For Word, Agent Mode provides instant assistance in writing and editing. A user can instruct Copilot to summarize a long report, expand notes into complete paragraphs, or restyle content for clarity. All of this happens directly in the document, allowing writers to maintain their workflow while receiving AI-powered refinements. Nadella emphasized that this integration helps users focus on substance and ideas, rather than formatting and structural details.

A step toward democratizing productivity
According to Nadella, the purpose of these upgrades is not to replace users but to enhance their capabilities. By automating repetitive steps and orchestrating multi-layered tasks, Copilot turns every Microsoft 365 user into a potential “superuser,” regardless of technical expertise. While questions remain about scaling the feature across organizations and handling larger datasets, Nadella’s demonstration highlighted a significant leap in how AI can augment workplace creativity and decision-making.

With Agent Mode, Microsoft 365 is no longer just about tools for writing, analyzing, or presenting. It is about orchestrating intent into outcomes, allowing users to work smarter and more strategically across Word, Excel, PowerPoint, and beyond.
