The main tool is Copilot in Excel; Analyze Data is a separate option for asking questions about a dataset and getting summaries or visualizations. Access depends on your Microsoft 365 plan, account, Excel version, platform, and—at work—administrator settings. Treat every AI result as a first draft: check the formula, filters, totals, and chart before relying on it.
What does AI in Excel do?
“AI in Excel” can refer to more than one feature. Copilot is Microsoft’s generative assistant for asking questions about a workbook and, in supported experiences, creating or changing workbook content. Analyze Data focuses on natural-language questions and suggested summaries and visuals. Both work best when the data is structured and the question is specific.
- Formulas: Ask Copilot to draft a calculation or explain an existing formula.
- Analysis: Ask for totals, comparisons, trends, or outliers in a named table.
- Cleaning and formatting: Request consistent capitalization, conditional formatting, sorting, or filters.
- Visuals and summaries: Ask for a chart, PivotTable, or summary table.
- Workbook edits: In supported Copilot experiences, request changes to worksheets, ranges, styles, or layout. Importing data from connected sources may depend on your account and configuration.
These capabilities do not mean Excel knows what your business terms mean. Define terms such as “profit,” “active customer,” or “overdue” in the prompt or workbook. Microsoft describes Copilot capabilities and supported experiences in its Copilot in Excel guide and data insights guide.
Which Excel AI feature should you start with?
| What you want to do | Good starting point |
|---|---|
| Ask a question about a clean dataset | Analyze Data or Copilot chat |
| Create or change workbook content | Copilot edit mode |
| See a proposed approach before changes | Copilot plan mode |
| Generate or understand a formula | Copilot |
| Find trends or outliers | Analyze Data or Copilot |
| Make a simple chart or PivotTable | Try Recommended Charts or Recommended PivotTables; Copilot is another option |
| Perform advanced statistical analysis | Copilot’s Python-based analysis, where available |
| No AI button appears | Check your account and eligibility, update Excel, check file and storage requirements, or try Analyze Data if available |
Copilot’s interface and feature set vary by account, platform, subscription, and rollout. Microsoft documents edit, plan, and chat-only modes; labels may differ in your Excel version. A standard Excel command is often faster for a one-step task. See Microsoft’s guide to editing with Copilot.

What you need before using Copilot
Copilot in Excel is documented for Excel for Microsoft 365, Excel for Microsoft 365 for Mac, Excel for iPad, and Excel for the web, but availability and capabilities are not identical on every platform. Microsoft lists multiple possible eligibility routes, including Microsoft 365 Personal or Family with an AI credits plan, Microsoft 365 Premium, a commercial Microsoft 365 Copilot subscription, and some Copilot Chat-eligible business or enterprise subscriptions. Do not assume that every Microsoft 365 user receives the same Copilot access or usage. Check Microsoft’s current Copilot in Excel FAQ for your account and plan.
- Sign in to an eligible account and use a supported, up-to-date Excel experience.
- Have an internet connection and permission to edit the workbook if you want Copilot to make changes.
- Some Copilot experiences require a modern workbook format, such as
.xlsx,.xlsb, or.xlsm, saved to OneDrive or SharePoint with AutoSave on. Requirements can vary by experience. - If this is a work or school account, an administrator may control access.
- Check your organization’s policy before using AI with customer, payroll, financial, health, legal, or other sensitive data.
As a price snapshot only, Microsoft’s U.S. individual pricing page listed Personal at $99.99 a year or $9.99 a month, Family at $129.99 a year or $12.99 a month, and Premium at $199.99 a year or $19.99 a month in August 2026. Prices, taxes, promotions, and plan contents can change; AI access and usage differ by plan, and Family AI benefits may not be shared with every member. Compare current terms on Microsoft’s individual plans page before buying. If you already have Excel, check whether your existing plan and Analyze Data are enough before paying for an upgrade.
Prepare your spreadsheet so AI can read it
A clean table gives AI clearer signals than a worksheet arranged mainly for presentation. To format a dataset as a table in desktop Excel:
- Click a cell in the dataset.
- Select Home > Format as Table.
- Choose a style, confirm whether the first row contains headers, and select OK.
- Select a cell in the table, open Table Design, and give it a descriptive name such as
SalesData.
Microsoft’s formatting guidance for Copilot recommends structured data. If you keep a regular range, use one header row with unique, nonblank names; avoid empty rows or columns, merged cells, and subtotals inserted into the data.
- Use clear headers such as
Order Date,Region,Revenue, andUnits Sold. - Make sure dates are real Excel dates, not text that merely looks like a date.
- Keep categories and names consistent, and make currency and percentage formats consistent.
- Remove accidental blank rows; decide whether duplicate records are valid before removing them.
- Keep notes and explanations outside the data table, and give calculated columns clear names.
Open Copilot and choose a mode
- Open the workbook in Excel and confirm that you are signed in to the account that has access.
- Select the Copilot button, commonly on the Home tab or near the lower-right of the window. Its location can vary.
- Choose a mode if your version offers one: Edit can make workbook changes; Plan proposes a structured approach before editing; Chat-only discusses or analyzes without changing the workbook.
- Enter a prompt, inspect Copilot’s response or proposed actions, and approve changes only when they match your intent.
For important work, begin in chat-only or plan mode, or make a duplicate of the workbook. Microsoft’s getting-started guide describes these modes and notes that feature availability can vary.
Write a prompt that gives Excel useful context
A reliable starting pattern is action + target data + conditions + desired output + constraints. Name the table and columns, say what to include or exclude, and specify how you want the result presented.
Too vague: “Analyze my sales.”
More useful: “Analyze the SalesData table. Summarize total revenue by region, identify the three products with the highest profit margin, and return a compact table.”
More specific: “In the SalesData table, compare monthly revenue from January through June 2026 by region. Exclude canceled orders, calculate the percentage change from January to June, identify regions with a decline, and create a line chart. Do not overwrite the source data.”
Free tools Windows power users keep installed
One-click scans. No signup required.
- Scope: “Use the
Expensestable.” - Task: “Calculate,” “compare,” “summarize,” “highlight,” or “explain.”
- Conditions: “Only active customers,” “exclude blank rows,” or “for Q2.”
- Output: “Return a table,” “create a PivotTable,” or “make a column chart.”
- Constraints: “Create a new worksheet and leave the source unchanged.”
- Checkability: “Show the formula and explain the assumptions.”
Microsoft likewise recommends specifying the data or columns and the desired output in its Copilot data-insights guidance.
Beginner examples: prompts to try
1. Generate a profit formula
Suppose a SalesData table has Product, Revenue, and Cost columns. Ask:
“Add a new column named Profit to the SalesData table. Calculate Revenue minus Cost for each row. Explain the formula.”
A structured-reference formula could be =[@Revenue]-[@Cost]. Then ask: “Add a column named Profit Margin using Profit divided by Revenue. Format it as a percentage with one decimal place.” Copilot may choose an equivalent formula depending on the workbook and locale, so inspect what it writes. For a row with revenue of 2,400 and cost of 1,350, profit is 1,050 and margin is 43.75%.

2. Explain a formula you did not write
For example, ask Copilot to explain =IFERROR(XLOOKUP(A2,Products[SKU],Products[Price]),"Not found") step by step, identify what each reference does, and explain what happens when there is no match. Test the explanation with a matching SKU, a missing SKU, a blank SKU, duplicate SKUs, and a price stored as text. A plain-English explanation is not a test of the formula.
3. Highlight overdue invoices
Ask: “In the Invoices table, highlight rows where Due Date is before today and Status is not Paid. Use a light red fill and dark red text. Do not highlight invoices marked Paid.” After the change, inspect the conditional-formatting rule and test a paid invoice and an unpaid past-due invoice. Copilot’s editing capabilities are described in Microsoft’s Copilot guide.
4. Find trends and possible outliers
Ask: “Analyze the SalesData table. Identify the months with the highest and lowest revenue, show the month-over-month percentage change, and flag any month where revenue is more than 20% below the average.” Check the date range, the definition of average, and whether canceled orders or blank months are included before treating the flags as meaningful.
5. Create a chart or PivotTable
For a chart, ask: “Create a line chart showing monthly revenue from the SalesData table. Put Month on the horizontal axis and Revenue on the vertical axis. Add a descriptive title and a legend by region.” Check the chart type, date order, aggregation, source range, labels, and units.
For a PivotTable, ask: “Create a PivotTable on a new worksheet showing total revenue by Region in rows and Month in columns. Add a filter for Product Category and sort regions from highest to lowest revenue.” Confirm that the value field is summed, not counted or averaged, and compare a result with a known total. Copilot can assist with charts and PivotTables, but the exact output depends on the workbook and account experience; see Microsoft’s visualization guidance.
Use Analyze Data if you do not have Copilot
Analyze Data is a separate Microsoft 365 feature for asking natural-language questions about a dataset and reviewing suggested tables, charts, PivotTables, trends, and patterns. In Excel, click inside the data and select Home > Analyze Data. Enter a question such as “Which product generated the most revenue?” or “Show total sales by region,” then review the suggested results and insert a useful visual if offered. On some older update channels, the feature may still appear as Ideas.
Microsoft documents Analyze Data for Microsoft 365 subscribers in English, French, Spanish, German, Simplified Chinese, and Japanese, with regional availability that may roll out gradually. Its support page says it does not support datasets over 1.5 million cells; it may misread dates stored as text and cannot analyze .xls compatibility-mode workbooks. See Microsoft’s Analyze Data guide for current limitations.
Verify AI-generated formulas, analysis, and charts
Copilot can produce inaccurate or unsuitable formulas, insights, and tables. Microsoft advises reviewing and verifying its output; a polished explanation is not evidence that the calculation is correct. Use a small, independently checked sample before applying a result to a larger or consequential workbook. Microsoft’s cautions appear in its visualization guidance and Copilot FAQ.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Check formulas
- Calculate at least one row by hand and compare it with the result.
- Inspect cell and table references, including whether the header or total row was included.
- Test blanks, errors, duplicates, and boundary cases.
- Confirm that text, dates, percentages, and currency are interpreted as intended.
Check summaries and analysis
- Confirm the correct table, filters, exclusions, and date range were used.
- Recalculate a total with a basic formula, a PivotTable, or a small manual sample.
- Check whether dates stored as text or data-entry errors changed the result.
- Make sure the analysis reflects your definitions of terms such as “late” or “profit.”
Check charts
- Confirm the aggregation is correct: sum, average, or count.
- Check chronological order, source range, labels, units, and filters.
- Look for duplicate totals, missing categories, or a misleading axis.
Fix common Copilot and data problems
Copilot is missing
First verify that Excel is signed in to the account with the relevant subscription. Update Excel, check your organization’s settings if it is a work account, and confirm any required file, OneDrive or SharePoint, and AutoSave conditions. Network, privacy settings, platform differences, and gradual rollout can also affect availability. If your account offers it, try Analyze Data instead. Microsoft lists these availability factors in its Copilot FAQ.
Copilot cannot analyze the data
- Convert the dataset to an Excel table, or select a supported range.
- Replace blank or duplicate headers with unique names.
- Remove merged cells, empty rows or columns, and subtotals inside the source data.
- Convert text dates to real Excel dates and check inconsistent data types.
- Check whether the workbook is in
.xlscompatibility mode or the dataset exceeds a feature’s limits.
Use Microsoft’s data-formatting guidance and Analyze Data troubleshooting details for feature-specific requirements.
A formula looks right but gives the wrong answer
It may reference the wrong column, treat text as a number, misread a date, use an unsuitable lookup match, mishandle duplicate keys, or apply a different business definition than you intended. Ask for a recheck without overwriting the existing calculation: “Recheck the formula using the Revenue and Cost columns only. Show the exact formula, explain each reference, and test it against the first three rows manually. Do not overwrite the existing column.” Then verify those rows yourself.
A chart looks misleading or a change was unwanted
Check the chart’s aggregation, sort order, source range, filters, and axes. Ask Copilot for alternatives if the chart type does not answer the question. If an edit is wrong, use Undo promptly; you can also ask Copilot to revise it. For important workbooks, use a duplicate or backup and, when available, restore a good version through OneDrive or SharePoint version history. Close without saving if necessary to discard changes since the last save.
Recommended Free Tools
Use AI safely, and know when ordinary Excel is better
Do not enter confidential or regulated information into an AI feature unless your employer or organization has approved that use. Microsoft notes that saved Copilot changes can be seen by people who have access to the workbook, including coauthors. Remove unnecessary personal information, preserve the original data, and document important assumptions and changes.
- Use Copilot when you want a first draft of a formula, an explanation, a multi-step edit, or a summary you can check.
- Use Analyze Data for natural-language questions and suggested visual summaries when it is available on your account.
- Use ordinary Excel tools when a formula, filter, PivotTable, Power Query, or Recommended Chart is quicker, more transparent, or easier to repeat.
- Do not rely on AI alone for accounting, tax, legal, medical, compliance, or other high-stakes decisions, or when you cannot validate the result.
AI is a drafting and analysis aid, not an autonomous accountant or an audit trail. For repeatable or audited work, record the prompt, assumptions, transformations, and checks you accepted.
