6.2 Generating a Document from an Existing Document

6.2 Generating a Document from an Existing Document

Quick Answer: The blueprint separates "create a new document from a prompt" from "generate a document from an existing document" because the risk profiles differ. Drafting from a prompt asks the model to supply both structure and substance. Drafting from a source document asks it only to re-express substance that already exists — which is why source-grounded generation is the default choice for anything containing figures, dates, or commitments.

Source-Grounded Generation (File-Referenced Drafting)

Source-grounded drafting anchors Copilot's generative process in verified organizational assets. By referencing existing files, Copilot extracts specific domain context, project milestones, budget figures, and stakeholder responsibilities, synthesizing them into a new document structure.

• Ideal Use Cases: Converting a raw project charter into a formal client proposal, synthesizing multiple meeting transcripts into an executive briefing memo, or turning a technical specification into a customer-facing product overview.
• The / (Forward Slash) Referencing Mechanism: Typing / in the "Draft with Copilot" dialog opens a dynamic file picker displaying recently accessed documents from OneDrive for Business and SharePoint Online. Users can select up to three reference files to ground the generation.

Exam Warning: Copilot in Word can only reference files stored in OneDrive for Business or SharePoint Online. Files stored on a local computer drive (e.g., C:\Users\Desktop\file.docx) that have not synchronized with the Microsoft 365 cloud tenant cannot be resolved by Microsoft Graph and will not appear in the / file picker.

1. In-Line Transformation & Iterative Refinement

Beyond drafting complete sections, Copilot in Word serves as an intelligent in-line editor. By highlighting any section of existing text, users unlock contextual transformation tools.

1. Rewrite with Copilot

Highlighting a sentence or paragraph and selecting the Copilot icon > Rewrite triggers an automated linguistic refactoring. Copilot generates multiple candidate revisions that enhance clarity, eliminate passive voice, and improve syntactic flow while preserving the core message.

2. Tone Shifting & Register Modification

Copilot provides pre-configured tone settings that instantly adapt selected text to different business contexts:

• Professional: Enhances formal vocabulary, enforces objective phrasing, and removes conversational idioms. Ideal for client proposals, executive summaries, and legal disclosures.
• Casual: Softens rigid structures, introduces conversational transitions, and enhances warmth. Suitable for internal team updates, newsletters, and informal project retrospectives.
• Concise: Aggressively removes filler words, eliminates redundancy, and condenses compound sentences into direct, punchy assertions. Designed for busy executives and high-impact briefing memos.

3. Modifying Length (Expand vs. Shorten)

• Expand: Instructs Copilot to elaborate on core concepts, add supporting justifications, or provide illustrative enterprise examples for high-level bullet points.
• Shorten: Compresses multi-paragraph explanations into executive summaries or single-sentence takeaways while preserving essential data points.

4. Visualize as a Table

Dense narrative text containing comparative metrics, product features, or step-by-step responsibilities can be overwhelming to read. Selecting unstructured text and choosing Visualize as a Table prompts Copilot to:

1. Analyze the underlying categorical dimensions in the text.
2. Create a formatted Word table with structured column headers.
3. Populate the cells with extracted facts, preserving numerical figures and owner attributions.

Reviewing a Derived Document

Transformation is not lossless. Copilot reliably preserves the main assertions of a source but can quietly drop the qualifiers that lawyers and auditors care about — "up to", "subject to board approval", "in the pilot region only". Before a derived document leaves your hands:

1. Diff the numbers. Every figure in the output should appear in the source. Any figure that does not is either inferred or invented.
2. Check the hedges. Search the source for conditional language and confirm it survived.
3. Confirm the scope. A summary that silently promotes a regional pilot into a company-wide programme is the most common and most damaging transformation error.

On the Exam: When a scenario involves an existing approved artifact — a contract, a policy, a signed proposal — the expected answer references that file rather than describing its contents in the prompt.
