Microsoft has rolled out its new Agent Mode for Excel and Word, promising to transform how users create complex spreadsheets and documents through AI assistance. However, the performance metrics and community response reveal significant concerns about reliability and practical implementation.
Accuracy Falls Short of Human Performance
The new Agent Mode in Excel achieved a 57.2% accuracy rate on SpreadsheetBench, a standard benchmark for evaluating AI spreadsheet capabilities. While this places it ahead of competitors like Shortcut.ai and ChatGPT's Excel agent, it still lags considerably behind human accuracy of 71.3%. This gap raises questions about whether the technology is ready for critical business applications where precision matters most.
The accuracy concern becomes more pressing when considering Excel's role in handling vital business data worldwide. Microsoft has acknowledged this challenge by implementing validation loops and ensuring that AI-generated sheets remain auditable, refreshable, and verifiable.
Community Skepticism About Vibe Working
Tech professionals have expressed mixed reactions to Microsoft's vibe working concept. Some view the approach as overly simplistic for complex analytical tasks. The community has drawn parallels to unrealistic expectations, comparing prompts like do a full analysis & find me insights to Hollywood's fictional enhance and zoom computer capabilities.
What's the rate of return according to our financial model? Let me vibe the answer for you. Just a sec.
This sentiment reflects broader concerns about whether AI can handle the nuanced requirements of financial modeling and data analysis that professionals rely on daily.

Technical Implementation Challenges
Users have highlighted fundamental issues with integrating AI into Excel's existing framework. Unlike version control systems that provide clear change tracking, Excel lacks robust diff capabilities, making it difficult to verify AI-generated modifications. The interconnected nature of spreadsheet data means that AI errors could cascade through multiple calculations and references.
Some community members suggest that effective AI integration would require a complete reimagining of Excel's architecture. They envision features like structured dependency trees and better state management, similar to 3D CAD software, which would make AI interventions more transparent and controllable.
The new features are currently available through Microsoft's Frontier program for Copilot customers and Personal/Family subscribers, initially limited to web versions with desktop support planned for later release.
