Introduction
Microsoft 365 Copilot can do more than create content from scratch. One of its most powerful capabilities is generating a new document based on one or more existing documents. Instead of manually copying information, restructuring content, or rewriting sections, users can instruct Copilot to analyze existing files and create a new document tailored to a specific purpose.
For the AB-730: AI Business Professional exam, it is important to understand that Copilot uses existing content as context to generate new drafts while respecting Microsoft 365 permissions and requiring human review of the final output.
What Does “Generate a Document from an Existing Document” Mean?
Generating a document from an existing document means using one or more files as source material for creating new content.
Examples include:
- Creating an executive summary from a lengthy report.
- Producing a project proposal from meeting notes.
- Creating training documentation from existing procedures.
- Developing a customer-facing guide from internal documentation.
- Turning a research paper into a presentation outline.
- Creating a status report from multiple project documents.
Rather than starting with a blank page, Copilot uses the referenced files as context for the generated output.
How Microsoft 365 Copilot Uses Existing Documents
When a user references a document, Copilot can:
- Read the information contained in the file.
- Identify key themes and topics.
- Extract important details.
- Organize information into a new format.
- Rewrite content for different audiences.
- Summarize or expand sections.
Copilot only accesses files that the user already has permission to view.
Typical Workflow
Step 1: Open Word with Copilot
Start a new document in Microsoft Word and open Copilot.
Step 2: Reference an Existing File
Examples:
- AnnualReport.docx
- Q2SalesAnalysis.docx
- MeetingNotes.docx
- EmployeeHandbook.docx
Step 3: Provide Instructions
Example prompts:
Create a one-page executive summary based on AnnualReport.docx.
Create a training guide using the information in EmployeeHandbook.docx.
Rewrite this report for a non-technical audience.
Step 4: Generate the New Document
Copilot creates a draft containing:
- Headings
- Structured sections
- Summaries
- Bullet points
- Recommendations
Step 5: Review and Refine
Users can continue improving the output through follow-up prompts.

This allows Copilot to combine information from multiple sources into one draft.
Human Review Remains Essential
Even when Copilot uses existing documents, users should still verify:
Accuracy
Ensure information was interpreted correctly.
Completeness
Confirm important details were not omitted.
Formatting
Adjust layouts and styles as necessary.
Tone
