Microsoft Adds ‘Vibe Working’ to Word and Excel

Vibe coding, which involves beginners generating apps by constructing a basic AI prompt, is likely familiar to everyone. Microsoft is now attempting to implement a similar technique for its Office programs. The software developer is introducing a new Agent Mode in Word and Excel that can create intricate papers and spreadsheets at the touch of a button. Today also saw the unveiling of a new Office Agent in Copilot conversation that uses Anthropic models to generate Word documents and PowerPoint presentations from a “vibe working” chatbot.

This introduction from Microsoft will allow employees to specify their preferences in a Word, Excel, or PowerPoint document via a Copilot prompt.

Why this matters these days is that with this generative AI, it can handle the difficult processes of data discovery and document creation a process Microsoft refers to as “vibe working.”

Sumit Chauhan, corporate vice president of Microsoft’s Office Product Group says “With Agent Mode in Office apps and Office Agent in Copilot chat, we’re bringing vibe working to Microsoft 365 Copilot today.” He also stated that, just as vibe coding revolutionised software development, Copilot’s most recent reasoning models enable agentic productivity for Office artefacts.

Microsoft’s Office programs now offer a more robust version of the Copilot experience called Agent Model in Word and Excel. It is intended to help non-expert users better understand Excel’s more complicated features. Chauhan asserts that “it’s not just simple assistive short answers but board-ready presentations or documents.” “To be honest, it’s work that a first-year consultant would complete in a matter of minutes.”

In essence, Agent Mode breaks down a difficult activity into manageable steps with planning and logic. Each stage of document generation is then divided into an agentic job and carried out using OpenAI’s GPT-5 paradigm. With everything it does shown in the sidebar, it’s similar to watching an automatic macro in real time.

Because the data it manages powers some of the most crucial components of organisations throughout the world, Microsoft has chosen a slow approach to integrating AI aspects into Excel. According to Chauhan, “[Agent Mode] enables you to create sheets that are auditable, refreshable, and verifiable.” “A lot of effort has been put into ensuring that the validation loop for each of these sub-agents is fairly tight.”

SpreadsheetBench, a standard for assessing an AI model’s proficiency in editing spreadsheets from the real world, reports that Microsoft’s Agent Mode in Excel has an accuracy rate of 57.2 percent. As a result, Agent Mode is ranked higher than Claude Files Opus 4.1, Shortcut.ai, and ChatGPT agent with.xlsx support. However, it still falls short of the 71.3 percent accuracy of humans.

Beyond Word’s built-in composing, rewriting, and summarising AI capabilities, Agent Mode offers more. According to Chauhan, “Word’s Agent Mode transforms document creation into vibe writing, an interactive, conversational experience.” It enables Copilot to draft material, make suggestions for improvements, and make clear what components are required throughout the document generation process.

For example, using data from prior months, it users can generate a monthly report, and Copilot can then summarise the month’s highlights and any variations from the previous report. According to Chauhan, “Copilot offers ideas to keep the process moving, so writing feels more like a conversation than a task.”

Through Copilot chat, Microsoft’s new Office Agent will also be accessible outside of its Office applications. It can generate complete Word documents or PowerPoint presentations from a chat prompt thanks to Anthropic models. One of the most popular tools for making presentations is PowerPoint, but Chauhan claims that within the past two years, AI has frequently failed to produce high-quality slides. “Office Agent modifies that.”

In addition to conducting web-based research and offering a real-time slide preview, Office Agent can produce completely organised PowerPoint presentations. It is Microsoft’s hope that Office will continue to set itself apart from the plethora of AI tools that are attempting to produce spreadsheets, slide decks, and papers.

Chauhan claims with the phrase saying “we are Office and productivity is in our DNA.” “There is no substitute for the real thing, even though others will attempt to imitate us.”

Anthropic AI models are also included into Microsoft 365 apps and services through Office Agent. Anthropic’s AI models can now generate Word and PowerPoint documents via Microsoft’s own Copilot chat interface, as Microsoft recently adopted the OpenAI competitor to enhance researcher, GitHub Copilot, and Copilot Studio.

In order to comprehend the strengths that various models offer and how we create the ideal composition for our goods, Chauhan states, “We are committed to OpenAI, but we are starting to explore with the model family.” “Everywhere innovative work is done, we are examining the whole family of models.”

It appears that Anthropic’s models are getting closer to being a significant component of Office programs like Word, PowerPoint, and Excel, even if OpenAI models still drive Microsoft’s AI efforts within Office products. Microsoft is integrating these functionalities into Copilot chat, which is powered by cloud rival Amazon Web Services, by utilising Anthropic’s API. This may be the reason why Anthropic’s AI models haven’t yet been extensively integrated into desktop Office applications.

Today, Microsoft 365 Copilot customers and Microsoft 365 Personal / Family members will be able to use Agent Mode in Copilot for Word and Excel in the Frontier program at their convenience. At debut, the Agent Model in Word and Excel is only accessible online; desktop functionality will be added soon. Today, Office Agent is also accessible to Microsoft 365 Copilot users and Microsoft 365 Personal / Family members in the United States through the Frontier program.
