The way we work is changing. No longer are professionals confined to manual, repetitive tasks that consume hours of productive time. Today, we’re entering a new era where artificial intelligence works alongside you, not just for you. At Marshall, we’re excited to break down what “vibe working” means and how Microsoft 365 Copilot’s Agent Mode and Office Agent are revolutionising the workplace.
Just as vibe coding transformed software development by allowing developers to work collaboratively with AI, vibe working brings that same collaborative spirit to everyday office tasks. Whether you’re creating spreadsheets, drafting documents, or building presentations, AI agents now handle the heavy lifting whilst you maintain creative control and strategic direction.
What is Vibe Working?
Vibe working represents a fundamental shift in human-agent collaboration. Rather than treating AI as a static tool that responds to individual commands, vibe working creates an iterative dialogue between you and intelligent systems. You provide initial direction through a simple prompt, then work collaboratively with Copilot as it orchestrates multi-step tasks, evaluates its own work, fixes issues, and refines outputs until they meet your standards.
Think of it as handing work to a specialist who understands your intent, asks clarifying questions, and delivers polished, professional results. You maintain oversight and creative control at every stage, steering the process towards your desired outcome.
Key Benefits of Vibe Working
- Democratisation of expertise: Complex tasks become accessible to everyone, not just specialists
- Faster iteration cycles: Move from concept to final output in minutes, not hours
- Higher quality results: AI agents evaluate and improve their own work iteratively
- Enhanced creativity: Focus on strategy and intent whilst AI handles execution
- Reduced cognitive load: Delegate routine work to focus on high-value decision making
Agent Mode in Excel: Democratising Data Expertise
Excel powers everything from household budgets to Fortune 500 profit and loss statements. Yet accessing Excel’s full potential has traditionally required expert knowledge. Agent Mode changes this entirely.
How Agent Mode Works in Excel
Agent Mode leverages OpenAI’s latest reasoning models combined with Excel’s native functionality. When you provide a prompt, Copilot doesn’t just generate a spreadsheet and stop. Instead, it:
- Decides which formulas to use based on your requirements
- Produces new sheets and organises data logically
- Creates data visualisations for insights
- Validates its own work and checks accuracy
- Iterates until results meet quality standards
- Provides a full summary of insights and validation steps
Microsoft’s benchmarking shows Agent Mode in Excel achieves 57.2% accuracy on complex spreadsheet tasks, demonstrating genuine capability in handling sophisticated data work.
Practical Agent Mode in Excel Prompts to Try
Financial Analysis
Create a financial monthly close report for a bike shop business. Include product line breakdown across vintage touring bikes, vintage touring frames, sequential analysis, and year over year growth calculations. Apply standard financial formatting and best practices with clear headers and professional layout.
Loan Calculator Development
Build a functional loan calculator that computes monthly payments based on user inputs for loan amount, annual interest rate, and term in years. Generate a complete amortisation schedule showing month number, payment amount, principal reduction, interest charge, and remaining balance. Present results in a clear, formatted table with currency symbols and two decimal places.
Personal Budgeting Tracker
Create a monthly household budget tracker with categories including Rent, Groceries, Utilities, Entertainment, Transportation, and Savings. Apply conditional formatting and data bars to show percentage over or under budget. Add a summary section comparing planned versus actual spending with a donut chart visualising spending distribution by category.
Why Excel Agent Mode Matters
For business professionals, accountants, analysts, and small business owners, Agent Mode eliminates the barrier to creating sophisticated financial models. What previously required hours of formula construction and troubleshooting now happens through natural conversation with an AI agent that truly understands Excel.
Agent Mode in Word: Collaborative Document Creation
Billions of Word documents are created every month across organisations worldwide. Agent Mode transforms document creation from a solitary writing task into an engaging, collaborative dialogue between you and Copilot.
The Vibe Writing Experience
Rather than staring at a blank page, you describe what you need. Copilot handles drafting, suggests refinements, asks clarifying questions, and maintains consistent formatting throughout. The experience feels like collaborating with a skilled colleague who understands your intent and brings it to life with professional styling and polished presentation.
How Agent Mode Enhances Word Documents
- Content generation: Copilot drafts substantive content based on your direction
- Data integration: Updates tables with latest information from referenced documents
- Formatting consistency: Applies title case, branding guidelines, and professional styles automatically
- Iterative refinement: Responds to feedback and makes targeted adjustments

Monthly Report Update
Help me update this monthly report for September. Update the data table with the latest numbers from the September Data Pull email. Summarise the key highlights including insights compared to last month’s August monthly report document. Maintain consistent formatting and professional tone.
Project Update Executive Summary
Update the executive summary for clarity and impact. Bold all key findings throughout the document. Insert a bulleted list of next steps based on the project update meeting notes. Make sure to add a strong conclusion that reinforces the main takeaways.
Document Style and Branding
Can you clean up this document? Apply title case for all section headers, implement branding updates per the latest brand guidelines email, and italicise all external partner mentions throughout. Feel free to ask if you need help identifying specific partners or guidelines.
Why Word Agent Mode Matters
Professionals spend considerable time formatting, updating, and refining documents. Agent Mode reclaims this time by handling the mechanical aspects whilst you focus on content strategy and decision making. The result is faster document completion, better consistency, and more time for higher-value work.
Office Agent in Copilot Chat: Presentation and Document Creation from Anywhere
Increasingly, work starts in chat. Office Agent in Copilot, powered by Anthropic’s advanced models, enables you to create complete PowerPoint presentations and Word documents through a chat-first experience without leaving Copilot Chat.
The Office Agent Creation Process
When you provide Office Agent with a creation request, it follows a structured process ensuring quality results:
1. Intent Clarification
Office Agent begins by understanding your prompt thoroughly. It asks about file length, visual theme preferences, key focus areas, target audience, specific requirements, and any constraints you’ve mentioned. This ensures the final output matches your vision precisely.
2. Deep Research Phase
Rather than relying on generic templates, Office Agent conducts web based research to gather relevant, current information. It reasons over this research material, showing you its chain of thought and providing a live preview of slides as it develops them.
3. High Quality Content Production
Using code generation and quality checks, Office Agent produces ready to share presentations or documents. You can then collaborate further to tweak visuals, adjust formatting, revise content, or seamlessly hand off to PowerPoint or Word for final touches using Copilot.

Business Plan for Pop Up Event
Help my restaurant chain draft a pop up kitchen plan in London. The event must serve 200 guests, use only locally sourced ingredients, stay within a 10,000 pound food cost budget, and comply with county health permits. Give me an 8 slide overview to help me through the planning process, including logistics, menu planning, and compliance considerations.
Retirement Savings Plan Employee Communication
I need to create a set of slides to share with my employees to encourage them to actively fund their retirement accounts. We’ve agreed to match a percentage of their contributions, but I’d like to increase the uptake of people participating in this programme. Use a combination of numbers, visuals, and narrative or analogies to help explain the benefits and create urgency.
Social Media and Influencer Marketing Report
Create a comprehensive report evaluating the trends of influencer and social media advertising in the coffee industry. Include emerging platforms, successful campaign examples, demographic targeting insights, and recommendations for brands looking to enter this space effectively.
Why Office Agent Transforms Presentation Creation
PowerPoint has long been a tool where AI struggled. Generic templates and poor slide design often resulted in presentations that looked amateurish. Office Agent changes this by creating tasteful, well structured decks that look professionally designed. Combined with deep research capability, Office Agent delivers presentations ready for boardroom delivery immediately.

The Future of Work is Collaborative
Vibe working represents more than a productivity boost. It’s a fundamental reimagining of human agent collaboration in the workplace. By handling routine tasks, data processing, and content generation, AI agents like those in Microsoft 365 Copilot free professionals to focus on strategy, creativity, and decision making.
The journey from prompt to polished output becomes a conversation rather than a transaction. You maintain creative control, strategic direction, and quality oversight whilst agents handle execution. This balanced partnership delivers better results faster than either humans or AI could achieve alone.
