has launched the Excel and Word that are controlled with prompts

Microsoft is trying to transfer the phenomenon of ‘Vibe Coding‘ – Write apps without knowing how to program, only with instructions to a chatbot – to office work. The bet is that anyone can do in minutes what I used to require hours of a junior consultant, without dominating Excel formulas or writing techniques.

• Agent mode In Excel, use OpenAI reasoning models to break down complex tasks in executable steps, as if an expert worked with you.
• Office Agentbased on Anthropic models, creates PowerPoint presentations and Word documents directly from Copilot chat.

The company says that agent mode in Excel reaches a 57.2% precision in Spreadsheetbench, surpassing Chatgpt agent and Claude Opus 4.1, although below 71.3% of human precision.

The context. Microsoft has been integrating the Office for months, but so far it was limited to specific assistance functions: summarize, rewrite, respond. Agent Mode and Office Agent mark a qualitative leap: IA assumes multipurpose tasks that previously required specialized knowledge.

Use OpenAI models for agent mode within the applications and anti -appoal applications and models for Cat in the chat. This division speaks of a certain diversification: Microsoft had already incorporated the Anthropic in Github co -ilot and Copilot Studio A few days ago

• Summit Chauhan, from Office, summarize it like this: “It is a job that a first -year consultant would do, delivered in minutes.”

Yes, but. The 57% accuracy in spreadsheet tasks leaves a considerable margin of error. Microsoft emphasizes that the results are auditable and verifiable, but still require human supervision for sensitive cases.

In addition, Agent Mode is only available in the Excel and Word web versions in the launch. The support for desktop applications will arrive “soon”, according to the company. Office Agent, meanwhile, is limited to users in the United States.

• The cloud services dependence also raises questions: Anthropic operates its API about AWS, Azure rival.
• This would explain why their models are not yet really integrated in Office desktop applications.

Between the lines. Microsoft presents this as democratization of access to expert capabilities. But it is also a way to justify subscriptions of Microsoft 365 Copilot. The relevant thing is that Microsoft is betting on AI doing heavy work while the user “guides and directs.” That is, the user goes from “doing” to “ask to be done.” What has already seen in programming, above all.

And there is another reading: if Agent Mode can do in minutes what he had been having been implicitable for hours before for hours. The question is what happens to who before that job. Specifically, with the Junior.

• Microsoft has designed this for the process to be visible: the user sees what is doing in each step, as if observing an automated macro in real time.

At stake. Microsoft competes against Google Workspacewhich also integrates generative in Docs and Sheets. But above all Now also competes against independent tools such as Notion AI, Gamma or Beautiful.AI, which promise to create presentations and documents from scratch without the need for Office.

Microsoft’s advantage is domain: one billion people use office every month. If you get Agent Mode to work well, you don’t need to convince anyone to change tool. Just update your subscription.
