Before You Start: What You’ll Need
Before jumping into the step-by-step tutorial, make sure you have the following in place:
- A Microsoft 365 Subscription — Most AI features, especially Copilot, require a Microsoft 365 Personal, Family, or Business plan. As of 2026, Microsoft Copilot Pro is bundled with Microsoft 365 at no extra cost for many plans.
- Excel Version 2024 or Later — If you’re using an older desktop version of Excel (like Excel 2016 or 2019), some AI features won’t be available. Use Excel Online (browser version) for free AI access with a Microsoft account.
- A Microsoft Account — Sign in at office.com to access Excel Online, which includes many free AI features.
- Your Data Ready — Have a spreadsheet (or sample data) ready to practice with. We’ll walk through examples throughout this guide.
| ✅ Pro Tip: Not sure if you have Copilot? Open Excel and look for the Copilot button in the Home tab ribbon. If it’s there, you’re good to go! |
Step 1: Enable and Access Microsoft Copilot in Excel
Microsoft Copilot is the most powerful AI tool in Excel right now. Here’s how to access it as a beginner:
How to Open Copilot in Excel:
- Open Microsoft Excel (desktop app or Excel Online at excel.office.com).
- Make sure your data is in a Table format. Highlight your data range, then go to Insert > Table and click OK.
- Click the Copilot button in the Home tab on the ribbon. It looks like a small sparkle or star icon.
- A Copilot sidebar will open on the right side of your screen.
- Type your question or request in plain English. For example: “Summarize the total sales by region.”
- Copilot will analyze your data and provide a response, formula, or chart — instantly.
| 📌 Important: Copilot in Excel requires your data to be formatted as a Table (not just a range). This is a common mistake beginners make. Always convert your data to a Table first using Ctrl + T. |
What Can You Ask Copilot in Excel?
Here are some beginner-friendly prompts you can type into Copilot:
- “Show me the top 5 products by revenue.”
- “Highlight all rows where sales are below $500.”
- “Add a new column that calculates profit margin.”
- “Create a chart comparing monthly sales for Q1 and Q2.”
- “Explain what this formula does: =VLOOKUP(A2, B:D, 3, FALSE)”
- “Find any duplicate entries in column A.”
Step 2: Use the ‘Analyze Data’ Feature for Instant AI Insights
Even without Copilot, Excel has a powerful built-in AI feature called Analyze Data (previously called Ideas). This tool automatically scans your data and generates meaningful insights, charts, and summaries — perfect for beginners.
How to Use Analyze Data:
- Open your Excel spreadsheet with data.
- Click anywhere inside your data table.
- Go to the Home tab and click on the Analyze Data button (on the far right side of the ribbon).
- A pane will slide open on the right with AI-generated charts, trends, summaries, and pivot table suggestions.
- Click Insert on any chart or insight you want to add to your worksheet.
For example, if you have a sales report with dates, regions, and amounts, Analyze Data might automatically show you:
- A bar chart comparing regional sales
- A trend line showing month-over-month growth
- A list of the top-performing salespeople
- An anomaly flag if one month’s data looks unusual
| 🔍 Why This Works: Analyze Data uses machine learning to find patterns in your data that you might take hours to discover manually. It’s like having a data analyst built right into Excel. |
Step 3: Let AI Write Formulas for You
If you’ve ever been frustrated trying to write a VLOOKUP or an IF statement, you’re going to love this. In 2026, you can now describe what you want in plain English and Excel’s AI will write the formula for you.
Method 1: Use Copilot to Write Formulas
Simply open the Copilot pane and type something like:
| 📝 Example Prompt: “Write a formula that calculates the average sales for the last 30 days.” |
Copilot will generate the formula with an explanation. You can then click Insert to add it to your spreadsheet.
Method 2: Use the Formula Bar AI Suggestions
When you start typing a formula in the formula bar, Excel now shows AI-powered suggestions based on your data context. This is similar to autocomplete, but smarter — it considers your column names and data types.
- Click on an empty cell.
- Start typing = followed by a description of what you need (e.g., =total sales by month).
- Excel AI will suggest matching formulas. Press Tab to accept a suggestion.
Method 3: Excel Labs — Formula Explainer
Microsoft Excel Labs (a free add-in from Microsoft Garage) includes an AI-powered Formula Explainer. Here’s how to use it:
- Go to Insert > Add-ins > Get Add-ins.
- Search for “Excel Labs” and install it.
- Click on any formula in your spreadsheet, then open Excel Labs.
- The AI will explain exactly what the formula does in plain English.
Step 4: Automate Data Cleaning with AI
Dirty data is one of the biggest challenges in spreadsheet work. AI in Excel can help you clean messy data quickly and accurately.
Flash Fill — Excel’s Built-In AI Pattern Tool
Flash Fill is one of Excel’s most underrated AI features. It recognizes patterns in your data and automatically fills in the rest. It’s available in all versions of Excel and requires no subscription.
Example: You have a column with full names like “John Smith” and you want to split them into First Name and Last Name columns.
- In column B, type the first name from the first row: “John”
- In column C, type the last name: “Smith”
- Go to column B, row 2 and start typing “Jane” — Excel will detect the pattern and preview-fill the rest automatically.
- Press Enter to accept the Flash Fill.
Flash Fill works for tasks like:
- Reformatting phone numbers (e.g., 1234567890 → (123) 456-7890)
- Extracting email domains from email addresses
- Combining first and last names into full names
- Changing date formats (MM/DD/YYYY → YYYY-MM-DD)
- Cleaning inconsistent capitalization
Using Copilot to Clean Data
With Copilot, you can ask it to clean your data with simple English commands:
- “Remove all duplicate rows in this table.”
- “Standardize the format of all dates in column B to MM/DD/YYYY.”
- “Replace all blank cells in column C with the value ‘N/A’.”
- “Remove extra spaces from all text in column A.”
Step 5: Create AI-Powered Charts and Visualizations
Visualizing data used to require significant Excel knowledge. Now, AI handles most of the heavy lifting for you.
How to Create Charts with AI Assistance:
- Select your data range.
- Go to Insert > Charts > Recommended Charts.
- Excel AI will analyze your data and suggest the most appropriate chart types.
- Browse the recommendations and click on the one that best fits your data.
- Click OK to insert the chart into your spreadsheet.
You can also use Copilot to create charts with a simple request:
| 📊 Example Prompt: “Create a line chart showing monthly revenue trends for the past 12 months with a trendline.” |
Copilot will generate the chart, format it, and even suggest a title — all automatically.
Sparklines — Tiny AI-Suggested Trend Charts
Sparklines are small, cell-sized charts that show data trends at a glance. They’re perfect for dashboards.
- Select the cells where you want sparklines to appear.
- Go to Insert > Sparklines > Line (or Column or Win/Loss).
- Select the data range and click OK.
- Excel AI will suggest formatting based on your data patterns.
Step 6: Use AI-Powered PivotTables for Data Summarization
PivotTables are Excel’s most powerful analysis feature — and AI has made them dramatically easier to use in 2026.
Create PivotTables with Copilot:
- Select your data table.
- Open the Copilot pane.
- Type: “Show me total sales by product category and region as a PivotTable.”
- Copilot will automatically create the PivotTable and insert it into a new sheet.
Use Recommended PivotTables (AI-Assisted):
- Click inside your data.
- Go to Insert > PivotTable > From Table/Range.
- In the dialog box, check “Add this data to the Data Model” and click OK.
- Excel will suggest pre-built PivotTable layouts based on your data structure.
- Choose the one that best answers your business question.
| 📈 Beginner Tip: PivotTables sound scary, but with AI assistance, you don’t need to configure them manually. Just describe what you want to analyze, and Copilot will build it for you. |
Step 7: Use Free AI Add-ins to Supercharge Excel

Step 10: Best Practices for Using AI in Excel as a Beginner
Now that you know the tools, here are the most important best practices to get the most out of AI in Excel:
- Always use Table format for your data — AI features work best with properly structured Excel Tables. Press Ctrl + T to convert any range.
- Be specific with your Copilot prompts — Instead of “analyze this,” say “Show me the top 10 customers by total order value in 2025.” Specificity gets better results.
- Verify AI-generated formulas before using — Always double-check formulas that Copilot writes. AI is helpful but not infallible.
- Keep column headers descriptive — AI reads your headers to understand context. “Total Revenue (USD)” is better than “Col3.”
- Save your work frequently — AI operations can sometimes crash Excel, especially with large datasets.
- Start small — Begin with a single AI feature and master it before adding more. Many beginners get overwhelmed trying to use everything at once.
- Use Excel Online for free AI access — If you don’t have a paid subscription, Excel Online at office.com gives you access to many AI features for free.
Common Mistakes Beginners Make with AI in Excel
Avoid these pitfalls that trip up most new users:
- Forgetting to format data as a Table before using Copilot — Copilot will show an error or give poor results if your data isn’t in Table format.
- Using vague prompts — “Analyze my data” gives vague results. Be specific about what you want.
- Ignoring AI suggestions — Many users dismiss Analyze Data suggestions without reviewing them. These insights can be genuinely valuable.
- Not checking formulas — AI-written formulas can sometimes reference the wrong cells or use incorrect logic. Always test them with known values.
- Skipping Flash Fill — This powerful feature is often overlooked. It can save enormous amounts of time on data formatting tasks.
