6 Ways to Master Document Creation and Analysis Using Copilot Chat in Microsoft 365
Remember the old office.com hub? It was a simple launchpad for Word, Excel, and PowerPoint. Microsoft has since transformed it into the M365 Copilot app, where the primary interface is now a powerful AI chat. Copilot Chat handles everything from drafting documents to analyzing data, while still giving you quick access to your files and apps via the sidebar. This article walks you through six key capabilities of this revamped hub, helping you leverage generative AI for your work. Whether you're creating a first draft or extracting insights from complex spreadsheets, Copilot Chat puts a virtual assistant at your fingertips.
1. The New M365 Copilot Hub: More Than Just a Launchpad
Microsoft's original web hub was designed to open Office apps and access recent files. Now, the M365 Copilot app places Copilot Chat front and center. The left sidebar still offers Search and Apps links, but the main purpose is conversation. You type a request—like "create a project proposal"—and Copilot responds with a generated document. This shift reflects Microsoft's investment in AI, making the hub an active workspace rather than a static gateway. For users on qualifying plans, the chat can also pull in data from your Microsoft 365 files, enabling dynamic workflows. The old office.com still redirects here, but the experience is entirely new.
2. Who Can Access Copilot Chat?
As of mid-2026, Copilot Chat is integrated into most Microsoft 365 plans, but access varies. For individuals (Personal, Family, Premium), only the subscriber account can use Copilot—it cannot be shared across family members. For business users, a basic version comes with M365 Business Basic, Standard, Premium, and enterprise Office 365 E1/E3/E5 or M365 E3/E5/E7 plans. Advanced features require an add-on Copilot license (included in M365 E7). Notably, Microsoft removed Copilot Chat from within Word, Excel, and PowerPoint for large enterprise users without an add-on license. Those users must use the M365 Copilot web app to chat. If you have no M365 subscription, you can still access files via the hub, but clicking "New chat" prompts an upgrade message.
3. Generate a First-Draft Word Document in Seconds
Using Copilot Chat, you can create a Word document from scratch without opening the app. Simply type a command like "Draft a business plan for a coffee shop startup". Copilot generates a structured document with headings, bullet points, and placeholder text. You can refine it by asking for more detail or a different tone. The result opens directly in Word Online for further editing. This feature uses Microsoft's Word AI agent, which understands context and formatting. It's ideal for overcoming writer's block or producing initial versions of reports, memos, and proposals. Just remember to review and personalize the content—AI drafts are starting points, not final products.
4. Build Excel Spreadsheets with Natural Language Commands
Copilot Chat can also generate Excel workbooks. For example, say "Create a budget tracker with columns for income, expenses, and totals". The AI builds a properly formatted spreadsheet, complete with formulas and sample data. You can then ask it to add more rows, apply conditional formatting, or create charts. This is powered by the Excel AI agent, which handles basic data structures and calculations. While complex analyses still benefit from manual expertise, this tool saves time on repetitive setup. The workbook is created in your OneDrive and can be opened in Excel Online or desktop. It even suggests pivot tables if you request summaries. Experiment with different prompts to discover its capabilities.
5. Craft PowerPoint Presentations from a Single Prompt
Need a presentation fast? Ask Copilot Chat to "Create a 10-slide PowerPoint deck about sustainable marketing trends". The AI agent generates slides with titles, bullet points, and suggested images. It can also apply a consistent theme from your organization's templates. You'll get a downloadable .pptx file in your OneDrive. This feature is especially useful for brainstorming initial slide structures or generating content for recurring reports. You can later refine each slide using Copilot in PowerPoint itself. The chat interface allows you to iterate quickly, asking for more slides on specific subtopics or a different layout. Just be prepared to adjust visuals and check facts—AI may occasionally invent statistics.
6. Analyze Files with the Advanced Analyst Agent
For subscribers with advanced Copilot licenses, the Analyst agent in Copilot Chat provides deep file analysis. You can upload or reference an existing M365 document (say, a Word report or Excel dataset) and ask questions like "Summarize this quarterly review" or "What are the top three sales regions by revenue?". The agent processes the file and returns structured insights, often with visualizations. This works with documents stored on OneDrive or SharePoint. You can even ask it to compare two files or identify trends. The Analyst agent uses natural language processing to understand context, making data exploration accessible to non-technical users. It also respects permissions—only files you have access to can be analyzed. This feature turns the hub into a powerful research assistant.
Conclusion
The M365 Copilot app has evolved from a simple app launcher to a comprehensive AI workspace. By integrating Copilot Chat, Microsoft enables document creation, spreadsheet building, presentation drafting, and file analysis—all through natural conversation. Whether you're a solo user or part of a large enterprise, understanding these capabilities can significantly boost your productivity. Start with a simple prompt and explore the document generation or file analysis features. As AI agents improve, expect even tighter integration with your daily tasks.
