Microsoft Copilot is changing the way millions of people operate with Office apps. Things that used to take hours – writing a complicated Excel formula, formatting a 30-page Word report, developing a flawless PowerPoint deck from scratch – may now be started, drafted, or completed in minutes by just telling it what you want in simple English. But as with any great technology, knowing that Copilot exists doesn’t mean you’re getting significant value out of it. You need to know how to utilize it well.

This tutorial provides a practical tour of how to use Microsoft Copilot in Excel, Word, and PowerPoint in 2026 – what Copilot can and can’t do in each app, the most useful features for the average user, and the prompting strategies that lead to the greatest outcomes.

What Is Microsoft Copilot?

Microsoft Copilot is an AI assistant incorporated right into Microsoft 365 apps – Excel, Word, PowerPoint, Outlook, Teams and more. It’s built on massive language models and fully connected into Microsoft Graph so it has access to your documents, email, meetings and calendar information to offer context-aware support.

One important difference between Copilot and merely running ChatGPT in a browser tab: Copilot runs inside your actual documents. It can read your Excel data, modify your Word draft, or expand on your existing PowerPoint slides-not just generate generic text that you then have to copy and paste.

Specifications

To utilize Copilot in Excel, Word and PowerPoint you will need:

• Microsoft 365 subscription (Business Standard, Business Premium or business plans)
• Microsoft 365 Copilot license (now an add-on for $30/user/month for enterprise; may be included in some consumer Microsoft 365 Personal/Family plans depending on where you live)
• Files in OneDrive or SharePoint (Copilot requires cloud-connected documents to work)

Using Copilot in Microsoft Word

In Word, most people find Copilot immediately useful because it solves the blank page problem better than nearly any other tool.

Writing Documents from Scratch

The most powerful Word Copilot feature is the first draft generation. To enter the Copilot window, click the Copilot icon in the toolbar or press Alt + I. Tell us what you want:

“Please write an executive summary for a company assessment for Q3. It should be one page and include sales performance, main problems and strategic priorities for Q4.”

Copilot writes an organized draft with proper headings, tone and duration. It’s not great — it will need editing, fact-checking, and customization — but it removes the most time-consuming portion of writing: starting.

Best practice: Provide Copilot with context. Write a report on “Write a 500 word report for a non-technical audience outlining why we’re shifting to cloud infrastructure, emphasizing on cost savings and reliability improvements.

Paraphrasing and Enhancing Existing Text

Select the Copilot icon and then select from the following: Highlight any text in your document.

• Rewrite – creates variations of highlighted text
• Summarize – turns selected text into bullet points
• Tone adjustment – makes selected text more formal, informal, succinct, or compelling

This can be very handy for editing – instead of rewriting problematic paragraphs yourself, pick them and ask Copilot to “make this more concise and direct.”

Long Document Summarization

Open any big Word document and ask Copilot in the sidebar:

• Summarize the 5 essential points in this document.
• List the major action items in this document.
• List the issues or dangers in this document.

This function alone saves a ton of time for anyone who receives long reports, contracts, or proposals they need to understand fast.

Use Your File to Generate Content

Copilot can also pull from other files in your Microsoft 365 environment:

• “Create a project launch email using the project brief in [file name]”
• “Draft this proposal’s methodology section with the study findings in [document name]”

That cross-document context is something only the Microsoft 365 Copilot integration can provide-you can’t do it with stand-alone AI products.

Questions About Your Paper

Copilot as a document analyzer:

• “Are there any provisions in this contract relating to the ownership of intellectual property?”
• “What information in this document leads to the suggestion we should move into the European market?”

This question-answer capability revolutionizes how you interact with extensive, complex research, legal and analytical materials.

Structuring & Formatting

” Mark this document with heading styles so it has a suitable outline structure. “

” Turn this bullet list into a properly formatted table. “

” Insert a table of contents based on the heading structure. “

In longer documents, formatting work is time-consuming to undertake manually, and Copilot can do it.

Using Copilot in Microsoft Excel

That’s where many users find the largest productivity improvements with Excel Copilot – particularly those who know what they want to do with their data but don’t speak the language of Excel formulas.

Understanding Data in Simple English

With your data open in Excel, enter the Copilot tab and tell it what you want to know:

• “Identify items with the greatest revenue growth from Q1-Q3”
• “Detect months where spending exceeded budget by more than 10%”
• “Average customer lifetime value by acquisition channel?”

Copilot reads your spreadsheet and either answers the query in text or generates charts and pivot tables to visually answer the question. This enables users who do not know how to develop pivot table queries to perform basic data analysis.

Constructing Formulas

One of the most immediately useful features of Excel Copilot: tell it what to compute and Copilot will write the formula.

• “Create a formula that calculates the year-over-year % change in revenue for each row.”
• “Create a VLOOKUP formula to get the customer name based on the customer ID located in column B, looking up the ID in the CustomerData sheet.”
• “Create a formula to sum sales only for the ‘West’ region and only where the product category is ‘Electronics’.”

Copilot tells you the formula and explains how it works . It solves your immediate problem , and helps you learn .

Important: Always validate formulas generated by Copilot before using them. Excel Copilot is remarkable, but not infallible. If you ask it to write complex calculations referencing several sheets, verify them with known values to ensure they are correct.

Chart and Visualization Creation

“Create a bar chart with monthly revenue by product category.”

“Add a trend line to this sales chart.”

“Design a dashboard with three charts: revenue by region, top 10 customers by revenue, and monthly growth rate.”

Copilot builds charts on your actual data, using the types of charts that match the structure of the data it sees.

Data Cleaning and Reshaping

Remove duplicate rows using the customer email column. Convert all dates in column C from MM/DD/YYYY format to YYYY-MM-DD. SSplit the ‘Full Name’ column into a ‘First Name’ column and a ‘Last Name’ column. Select all rows where the value in column D is blank.

Now, Copilot can explain and perform data purification procedures in natural language that would previously have required Power Query skill or manual work.

Tricks of Conditional Formatting

“In the profit margin column, the cells should be highlighted in red if the margin is less than 15%.

“Apply a color scale to the revenue column from green (highest) to red (lowest).

Adding Calculated Columns

“Add a column that labels each transaction as ‘High’ (above $10,000), ‘Medium’ ($1,000–$10,000) or ‘Low’ (under $1,000).”

“Add a column that calculates the number of days between the order date and the delivery date.”

Copilot writes the formula, inserts the column and labels it – all in a single instruction for multi-step operations.

Insights Without Knowing What to Look For

“What trends or abnormalities have you seen in this data?”

“What do you suggest I look at more deeply in this dataset?”

These open-ended inquiries can reveal trends that you didn’t know to search for-handy for exploratory data analysis.

How to Use Copilot in Microsoft PowerPoint

PowerPoint Copilot addresses one of the most time-consuming jobs in business: building presentation decks from scratch or from existing content.

Making a Presentation from a Prompt

Open PowerPoint and choose “Create presentation with Copilot.” Tell it what you want:

Create a 10-slide quarterly business review presentation that covers sales performance, client retention, product changes, and Q4 priorities.

Copilot creates a whole presentation with slide titles, content, structure and design – structured and ready to update. The presentations utilize dummy text built from your prompt, which you replace with real data.

Best practice: The more detailed you are in your prompt, the better the output will be. The audience. Executive leadership team. The purpose. To seek permission for a new marketing budget. The length. 8 slides. The tone. Professional and data driven.

To Make a Presentation from an Existing Document

That’s one of the strongest PowerPoint features of Copilot:

Create a PowerPoint presentation from [Word document or PDF] data.

Copilot analyzes the source content and produces a structured presentation by pulling out the important information, organizing them into slides, and adding suitable design. A 20-page study report turns into a 10-slide presentation in minutes.

It works with Word documents and PDFs you open in your OneDrive or SharePoint, and it turns long-form writing into a visual, presentation-ready format.

Adding Slides to an Existing Presentation

Add a slide that summarizes the competitive landscape, in between the market overview and strategy slides. Add a slide with 3 key takeaways at the end of this presentation. Add an agenda slide at the beginning with all the main sections.

Copilot inserts slides that are consistent with the design of the existing presentation.

Changing and Improving Slide Content

Click any slide or text object and tell Copilot to:

• “Limit this list to five words per bullet.”
• “Rewrite the content on this presentation to be more appealing for a sales audience.”
• “Simplify this slide for a non-technical audience.”

Presentations: Reorganize and Summarize

“Create an executive summary slide for this 20-slide presentation.”

“What is the major point the presentation is trying to make?”

“Rearrange these slides to make the story flow better.”

Copilot’s analytical ability enables a quick understanding of the information and improvements to it for revising inherited presentations or assessment of decks before sharing.

Creation of Speaker Notes

“Add speaker notes to each slide with background and talking points to elaborate on the bullet points.”

“Add speaker notes to the last slide with a call to action and next steps.”

Creating speaker notes is sometimes the most time-consuming part of preparing a presentation – and Copilot can do it for you effectively.

Design Tips

“Make this presentation look better by proposing design improvements.”

“Change the color scheme to our brand colors: blue (#0052CC) and white.

Copilot’s design powers are not as strong as its content capabilities, but it can make simple formatting modifications and propose improvements.

How to Prompt Microsoft Copilot Successfully

The quality of your prompts is a big factor on the quality of Copilot’s output. These strategies are always beneficial:

• Know your target, know your purpose. “Write a product announcement” returns generic output. Subject: Security Enhancements in Our Latest Software Release Dear Enterprise IT Managers, We are pleased to report significant security improvements in our latest software release.
• Indicate the format and length. Tell Copilot if you want bullet points or prose, how many items, and what length. “summarize in 3 bullet points of 15 lines or less” is more beneficial than “summarize”
• Provide context. The background scenario and limits are described in the other files. The more context that Copilot possesses, the more relevant its output will be.
• Iterate, don’t expect perfection. Use Copilot’s first output as a starting point. Ask it to do things like “Make this more formal,” “Add a section on implementation timeline,” or “Shorten by 30%.”
• Ask for clarifications. In Excel, Copilot will explain its formulae and logic so you can verify accuracy and learn.
• Always check and cross-check. Copilot may generate reasonable sounding text that contains inaccuracies, outdated information, or unsuitable conclusions. All output is reviewed by a human, before it is used.

Copilot’s limitations

Keep your expectations modest to avoid disappointment:

• Copilot doesn’t have access to the internet for real-time information – it’s reliant on your documents and its training data.
• Excel Copilot can sometimes provide you formulas that produce problems. Always try difficult calculations on test data.
• PowerPoint’s design capabilities are limited – Copilot will create usable slides, but it won’t replace professional design work.
• Copilot needs files to be saved to the cloud – it does not work with locally saved files that have not been saved to OneDrive or SharePoint.
• Edit outputs – Copilot drafts are beginning points, not finished products.

Final Thoughts

Microsoft Copilot in Excel, Word, and PowerPoint is a real productivity game-changer for anyone who spends a lot of time in these apps. The best work it does – creating documents, analyzing data, generating calculations, building presentations – is exactly the work that takes disproportionate time relative to its strategic importance.

Start with one application, one workflow. Word is also the most natural place for most people to start – try asking Copilot to write or summarize something you’re already working on. Once you’re comfortable prompting and examining output in one application, expand to Excel and PowerPoint. After a couple of weeks of frequent use, most users find it hard to work without it.
