Copilot in Word, Excel & PowerPoint

How Copilot actually works inside the three documents apps you use most. What it can see, what it can do well, what it can't, and the prompts that earn it a place on your desktop.

What Copilot Sees, in Each App

The thing that makes Copilot different from the free consumer chatbots is that it can already see the work in front of you. You don't need to paste, copy, or upload. The file you have open is the context.

In Word, Copilot sees the current document. It can read all of it, summarise, rewrite, continue, and edit.

In Excel, Copilot sees the active worksheet. It can analyse your data, suggest formulas, and generate charts, but it works best when your data is in a proper Excel Table (see the Excel session).

In PowerPoint, Copilot sees the current deck. It can generate slides, rewrite content, adjust design, and turn a Word document into a first-draft deck.

Copilot is an AI that knows what's in front of you. Your job is to tell it what to do with that.

// licensing

A Note on Licensing

"Copilot" means several different things, and the one you have depends on your organisation's licence.

Free Copilot (copilot.microsoft.com, or the Copilot button in some Windows and Edge versions) is a general chat tool, not connected to your documents. Fine for general questions, not what this session is about.

Microsoft 365 Copilot (the paid add-on, or "M365 Copilot") is the version embedded inside Word, Excel, Outlook, Teams, and PowerPoint. It can read and act on your content. This is the one this session assumes.

Copilot for specific apps like "Copilot in Word" or "Copilot in Excel" are the same M365 Copilot, just accessed inside that app.

If your ribbon doesn't have a Copilot button in Word, Excel, or PowerPoint, your organisation likely doesn't have the paid licence yet. The prompts and patterns below still apply, you'd just be running them through the free web Copilot with content pasted in, which is fine for non-sensitive work.

Check your organisation's policy before heavy use

Some organisations have M365 Copilot turned on but with guardrails (certain sites or SharePoint content is excluded). Others have it in pilot for a team only. Know what your arrangement is before relying on it for sensitive work.

Copilot in Word

The tasks where Copilot in Word earns its keep. None of these replace good writing. They save the empty-page minutes, the reformatting minutes, and the "how do I summarise this 40-page thing" minutes.

Draft from a prompt

Start a document from a description, not a blank page

Copilot can generate an entire first draft from a short brief. It'll produce structured output (headings, paragraphs), usually in a reasonable tone, always in need of some edits.

Draft a one-page briefing note for a senior manager on options for moving our paper-based incident log to a digital system. Include a background paragraph, three options (low cost, moderate, full replacement), pros and cons for each, and a recommendation. Australian English, plain language, no corporate jargon.
Summarise an existing document

Turn a long document into what you need to know

Open the document, ask Copilot for what you actually want. Not just "summarise", but the specific thing you need.

Give me a plain-English summary of this document in under 200 words. Include the three main findings, who the recommendations are aimed at, and what a program manager in my position needs to actually do about this.
Rewrite

Adjust tone, length, or reading level

Highlight a paragraph, click Copilot, tell it what to change. Good for taking something formal and making it plain, or the reverse.

Rewrite this paragraph in plain English for an audience who doesn't know government jargon. Keep the facts and the ask, drop the filler.
Ask questions of the document

Interrogate a document instead of scanning it

Instead of Ctrl+F and hoping to guess the keyword, just ask.

Does this document say anything about training obligations for remote staff? If yes, quote the exact sentences. If not, tell me.
Generate structure

Build an outline you then fill in

Particularly good for repeated document types. Grants, reports, briefings, policies.

Give me a standard outline for a grant acquittal report, section by section. For each section, one sentence on what goes in it. Leave headings I can fill in.
Good Word structure pays off here

Documents with real heading styles (see the Word session) produce noticeably better Copilot output. A document where headings are "just bold text" confuses it. A document with clean Heading 1, 2, 3 styles lets Copilot navigate and summarise far more reliably.

// excel

Copilot in Excel

Excel is where Copilot either shines or fails hard. The difference is entirely whether your data is shaped like a Table (see the Excel session). Clean, columnar data: Copilot is brilliant. Merged cells, stacked headers, blank rows: Copilot flounders.

Natural-language formulas

Describe the formula you want

Instead of remembering the exact syntax, describe the result.

Add a column that shows total budget for each region, summed across all programs in this Table. Use a formula that uses column names, not cell references.

Copilot will produce something like =SUMIFS(Programs[Budget], Programs[Region], [@Region]), and drop it into the right cell.

Find patterns

Ask what's in the data before you know what to ask

Great for "I've been handed a spreadsheet and need to figure out what matters."

Look across this sheet and tell me: what are the three most interesting patterns or outliers? Which rows look unusual compared to the rest? Are there any columns that seem inconsistent or poorly formatted?
Clean up data

Tidy a messy import

Especially useful for data pulled out of other systems.

In this sheet, column C mixes dates written several ways (some as text, some as proper dates, some with slashes, some with dashes). Please standardise the column to ISO dates (YYYY-MM-DD) and flag any rows where the original value is unclear.
Chart generation

First-pass charts from a description

Copilot can produce a chart from your Table and let you refine it from there.

Make me a bar chart showing total participants by region across all Active programs. Sort the bars from highest to lowest. Put the region name under each bar, and label the y-axis "Participants".
Analysis

Ask questions in English, get numerical answers

The answer is grounded in your data, not made up.

Looking at this Table, what's the average budget per participant across all Active programs? Which region has the highest, and which the lowest? Give me the numbers and point out if any are outliers worth investigating.
Verify before you trust numbers

Copilot in Excel is grounded in your data, but it can still make arithmetic mistakes or misinterpret a column. For anything where the number matters, spot-check one or two against a manual calculation before using the answer. Trust but verify.

// powerpoint

Copilot in PowerPoint

PowerPoint is where Copilot feels most magical and sometimes most misleading. It can generate a deck from nothing in seconds. Whether the deck is good is a different question.

Deck from a document

Turn a Word document into a draft deck

The killer feature. If you have a Word document with clean heading structure, Copilot can turn each section into a slide.

Turn the attached Word document into a 10-slide presentation. Use one slide per main section. First slide is the title. Last slide is recommendations. Keep the tone professional but not dry. Use bullet points sparingly.
Deck from a brief

Start with a description, get a first draft

Good when you don't have a source document but know roughly what the deck needs to cover.

Create a 6-slide deck for an internal team update on our digital skills training rollout. Slides: title, why we're doing this, what we've delivered, feedback so far, what's next, questions. Keep text minimal, suggest a simple image for each slide.
Rewrite and tighten

Fix a dense slide

The classic corporate problem: slides with too much text. Copilot can cut ruthlessly.

This slide has too much text. Rewrite it so the main point is the headline, and the rest fits in three short bullets or less. Keep the facts, lose the filler.
Speaker notes

Generate notes for each slide

Often more useful than the slides themselves, because the slides are for the room and the notes are for you.

For each slide in this deck, write 3-4 sentences of speaker notes. Notes should sound natural when read aloud, expand slightly on each bullet, and include one thing I shouldn't forget to say. Not a script, more of a prompt.
Generated decks always need editing

Copilot in PowerPoint will produce a plausible-looking deck from almost anything. It may also include bullet points that overstate, imagery that's generic, or structure that's fine for a template but wrong for your specific audience. Treat the output as a scaffold, not a finished product.

// review

Reviewing What Copilot Produces

The same "human in the loop" principle from the AI Foundations session applies, harder, in the document apps. The AI produces polished-looking output that sounds right whether it is or not. Your review is the last gate.

The review pass

The AI drafts, you decide. If it goes out with your name on it, the responsibility is yours.

// judgement

When to Reach for Copilot, When Not To

Not every task is a Copilot task. Knowing the difference saves you from both underusing and overusing.

// Good Copilot tasks
  • First drafts, summaries, rewrites, outline generation.
  • "What does this say and what's it asking me to do."
  • Rough chart generation and natural-language formulas.
  • Plain-English translation of policy.
// Bad Copilot tasks
  • Anything requiring current external information it doesn't have.
  • Anything involving a sensitive interpersonal situation.
  • Anything where the exact wording carries legal weight.
  • Anything where the value is your personal judgement or authorship.

Tasks where Copilot is a time trap: anything simple enough that you'd write it faster than you'd prompt, anything so specific that you'd need to write most of it as context anyway, anything where the AI's first draft will be close enough that you don't critically review it.

// practice

Practice Prompts

A short set of prompts worth trying on your own work after the course. Save them to your prompt library (see the Prompting Skills session).

Word, summarise a real document

Summarise this document in 150 words for someone in my role. Include the three most important points, what's being asked of us, and one thing I should flag to my manager.

Word, rewrite a section you've been stuck on

I've drafted this paragraph but it's not working. Please rewrite it three different ways: one more formal, one more direct, one warmer. I'll pick the closest and ask you to refine.

Excel, ask the sheet a question

Looking at this sheet, what are the top three things I should be paying attention to? Any data quality issues? Any rows that look like mistakes or outliers?

Excel, add a formula in words

Add a new column that calculates the difference between the planned budget and the actual spend, and flags any row where the difference is more than 10 percent.

PowerPoint, Word to deck

Convert the attached document into a 6-slide presentation for a team meeting. Keep slides visual and sparse. Include speaker notes for each slide.

PowerPoint, tighten a slide

This slide is too dense. Rewrite it with a clear headline stating the main point, followed by no more than three short bullets. Move the rest to speaker notes.
