Working with Existing Documents
Turn a 20-page report into a 1-page executive summary. Generate new documents from existing ones. Learn how Copilot transforms content you already have.
Transform what you already have
You don’t always start from scratch. Sometimes you have a document and need Copilot to turn it into something else:
- A 20-page report → a 1-page executive summary
- A Word document → a PowerPoint deck
- A technical spec → a client-friendly overview
- Last quarter’s report → this quarter’s template
Copilot excels at these transformations because it understands structure, tone, and audience. You point it at the existing document and tell it what you want out the other side.
Generating from an existing document
Word → PowerPoint
In PowerPoint, you can create a presentation directly from a Word document:
- Open PowerPoint → click Copilot
- Select “Create presentation from file”
- Choose your Word document
- Copilot extracts headings, key points, and structure → generates slides
Document → Different audience
In Word, you can transform content for a different reader:
- “Rewrite this technical specification as a client-friendly overview. Remove jargon, focus on benefits, keep it to 1 page.”
- “Turn these meeting notes into a formal action plan with owners and deadlines.”
Last period → This period
Use an existing document as a template for new content:
- “Based on the Q2 marketing report /Q2-Marketing-Report.docx, create a Q3 version. Keep the same structure but update the timeframe references and leave placeholders for new data.”
Real-world: Marcus's report-to-deck transformation
Marcus at Horizon Logistics writes a detailed quarterly operations report (15 pages). The leadership team wants a 10-minute presentation, not a document.
Old way: Marcus spent 3 hours manually extracting key points, creating slides, adding charts.
With Copilot: He opens PowerPoint and says: “Create a presentation from /Q3-Operations-Report.docx. Focus on: delivery performance, warehouse efficiency, and cost trends. 8 slides. Include the key metrics and one chart per data section.”
Copilot generates the deck in 30 seconds. Marcus spends 20 minutes refining — updating a chart, adjusting a few talking points.
Time saved: 2.5 hours per quarter.
Generating management summaries
Management summaries are one of the most common Copilot use cases. Leaders need the essence, not the detail.
How to generate a summary
In Word with a document open:
- “Summarise this document in 5 bullet points for the CEO”
- “Create a one-paragraph executive summary highlighting the key recommendation and supporting data”
- “Generate a management briefing from this report. Focus on: what changed, what it means, and what we should do next.”
Summary types
| Summary Type | Prompt Pattern | Best For |
|---|---|---|
| Bullet summary | Summarise in N bullet points | Quick email updates, meeting prep |
| Executive summary | Create a one-paragraph executive summary | Report cover pages, leadership briefs |
| Action-oriented | Summarise decisions and next steps | Post-meeting documents, project updates |
| Comparative | Compare this document with /previous-version.docx | Change tracking, quarter-over-quarter analysis |
Exam tip: “Generate a management summary based on a document” is a specific exam objective. Know that Copilot can produce different summary styles (bullet, executive, action-oriented) and that you should specify the audience and format for best results.
