Discover the new agentic capabilities of Microsoft 365 Copilot that enable direct editing in your Excel, Word, and PowerPoint files.

A Revolutionary Approach to Collaborative Work

Real work is inherently iterative: contexts evolve, modifications accumulate, and version proliferation quickly becomes unmanageable. Microsoft 365 Copilot addresses this reality with a fundamentally new approach. AI is now agentic, collaborating with you to execute multi-step actions directly in Excel, Word, and PowerPoint, where you already work.

i

Major Update

With Work IQ, Copilot remains anchored in your current data across your files, meetings, conversations, and professional relationships, ensuring optimal contextual consistency.

This evolution transforms how teams collaborate. Modifications are applied directly to the source file, transparently, verifiably, and reversibly. This approach enables teams to co-create and refine a single version rather than circulating multiple copies.

Security remains a priority: Copilot respects Microsoft 365 permissions and sensitivity labels. With the integrated model selection, you can adapt the appropriate model to each task without switching tools.

Excel: Advanced Modeling and Scenario Analysis

Copilot in Excel revolutionizes scenario modeling, input data updates, and trend identification by editing directly in your workbook with native tables, formulas, and charts.

Key Features

The objective goes beyond simply answering: it's about creating a reliable working model. Copilot applies updates directly to the grid, allowing you to review changes, adjust assumptions, and iterate as input data evolves.

✦

Model Selection

You can now choose between OpenAI or Anthropic models for in-app editing, optimizing performance based on the task.

This experience supports locally stored workbooks, file downloads, and file search. Work IQ grounding will be deployed this month, followed by additional model options including GPT-5.4 and Claude Opus 4.6 in the coming weeks.

Practical Use Cases

1

Creating Financial Forecasts

Generate a complete P&L forecast using the latest data from a reference file, including revenue, cost of goods sold, and operating expenses over 12 months with adjustable assumptions.

2

Refreshing Performance Data

Replicate the previous week's analysis in a new sheet with the latest figures, creating visualizations of customer churn trends and clearly identifying concerning areas.

3

Valuation Modeling with Sensitivity Analysis

Create a discounted cash flow model with sensitivity analysis tables, scenario selectors, and standard financial formatting.

Availability: Generally available today in Excel for Windows, web, and Mac for Microsoft 365 Copilot users.

Word: From Draft to Final Document

Copilot in Word transforms working drafts into review-ready documents. It works in the same document your team is editing, enabling co-creation and iteration without creating or reconciling multiple copies.

Intelligent Editing Capabilities

Ask Copilot to update or complete a document based on a template, add an executive summary, and suggest changes incorporating stakeholder feedback. It can restructure sections, rewrite for clarity, and apply native Word styles to facilitate review.

!

Work IQ in Action

With Work IQ, Copilot maintains document alignment with your most recent work context (decisions, dates, details), reducing reconciliation time for updates.

Optimized Use Cases

  • Creating project status reports: Automatic generation of structured briefs with dedicated sections and identification of missing elements
  • Updating recurring executive reports: Automatic replacement of previous month's data with the latest updates
  • Finalization and formatting: Harmonization of structure, formatting, and tone according to organizational standards

Availability: Generally available today in Word on Windows, web, and Mac. OpenAI and Anthropic model selection will be available in April.

PowerPoint: Co-Creating Brand-Compliant Presentations

PowerPoint introduces Copilot editing experiences for co-creating clear, visual presentations that comply with brand identity.

Respecting Visual Identity

Copilot respects organizational templates and themes by using approved colors, layouts, object styles, and images. Presentations remain consistent without additional effort.

1

Message Optimization

Use Copilot in existing presentations to refine a slide's main message and simplify dense bullet points.

2

Visual Transformation

Convert text into clearer visuals like timelines, diagrams, and charts without complete redesign.

3

Brand Consistency

Automatically verify compliance with organizational brand guidelines.

Upcoming Features

The experience will continue to expand with:

  • OpenAI and Anthropic model selection
  • Explicit anchoring in your files, emails, meetings, and conversations
  • Implicit integration via Work IQ

Availability: Rollout in progress on web for Microsoft 365 Copilot users. Windows and Mac will follow in the coming months.

A New Era of Collaborative Productivity

This evolution of Microsoft 365 Copilot addresses the real needs of modern work: transforming work in progress into shareable results—review-ready documents, reliable models, and brand-compliant slides.

✦

Additional Resources

Consult the official documentation for editing with Copilot in Excel, Word, and PowerPoint, as well as brand kit management guides to optimize your experience.

Copilot's agentic approach marks a decisive turning point in the evolution of artificial intelligence serving professional productivity, offering more natural and efficient human-machine collaboration.
