With new agent mode for Excel and Word, Microsoft touts “vibe working”
With a new set of Microsoft 365 features, knowledge workers will be able to generate complex Word documents or Excel spreadsheets using only text prompts to Microsoft's chat bot. Two distinct products were announced, each using different models and accessed from within different tools-though the similar names Microsoft chose make it confusing to parse what's what.
Driven by OpenAI's GPT-5 large language model, Agent Mode is built into Word and Excel, and it allows the creation of complex documents and spreadsheets from user prompts. It's called "agent" mode because it doesn't just work from the prompt in a single step; rather, it plans multi-step work and runs a validation loop in the hopes of ensuring quality.
It's only available in the web versions of Word and Excel at present, but the plan is to bring it to native desktop applications later.
