Microsoft Copilot in Excel vs Analistable

What each tool is for

Copilot's strengths inside Excel

Copilot is built into the Excel ribbon and sees the workbook you are working in. It can suggest a formula column (“add a column with margin %”), apply conditional formatting, build a PivotTable or chart, and summarise trends. Because it acts on the sheet itself, the result stays in Excel where your colleagues already look, with normal formulas they can audit.

Microsoft has been extending it with Python in Excel for heavier analysis and with features that work across more of the workbook. Capabilities change frequently, so check Microsoft's current documentation for your version rather than relying on any list, including this one.

Licensing and data requirements

Copilot in Excel is not part of every Microsoft 365 plan. Business users generally need a Microsoft 365 Copilot add-on licence; some consumer plans include Copilot features with usage limits. Availability differs by plan and region and has changed several times, so confirm with your admin.

• Copilot has historically required the file to be saved to OneDrive or SharePoint with AutoSave on; check whether this still applies to your setup.
• It works best when data is in a clear tabular range or a formatted Excel table with one header row.
• Data is processed within Microsoft's cloud under your organisation's Microsoft 365 terms, which many IT teams already approve.

That last point is a genuine advantage: if your company has approved Microsoft 365 Copilot, using it may need no new security review at all.

Prompts Copilot handles well

These are tasks you could do yourself in a minute or two; Copilot saves the clicks and helps people who do not remember the formula syntax. The suggestions are still worth checking: a margin column that divides by the wrong field looks just as confident as a correct one.

Limits worth knowing before you rely on it

• It needs reasonably clean data. Blank header cells, merged headers or several tables on one sheet reduce the quality of its suggestions.
• It works on what is in the workbook. Data in another file, a database or Google Sheets has to be imported first.
• Answers are generated, so the same prompt can produce a slightly different formula or chart on another day. Keep the version you checked.
• Very large ranges may be summarised rather than fully analysed; Microsoft documents size guidance that changes between releases.

None of these are unusual for AI assistants; they apply in some form to every tool on this page, including Analistable, which is why showing the underlying formula or SQL matters.

Where cross-file questions get harder

Copilot reasons about the open workbook. If the answer needs a CRM export, a finance workbook and a Google Sheet, you first have to bring them together, typically with Power Query or by pasting into one file, then ask Copilot. That works, but the combining step is manual. Our guide to Excel's Data Model relationships shows how to set up the join so a PivotTable can use it.

Analistable starts from the multi-source case. Each file or sheet becomes a table in a DuckDB database inside your browser; the AI sees only the schema and writes SQL that joins them. It does not write back, so the source workbooks stay untouched.

Worked example: renewals at risk

Question: which customers renewing next month have more than three open support tickets? The data lives in renewals.xlsx (finance) and a ticket export CSV (support).

Three customers, £48,600 of ARR at risk. In Excel with Copilot you would import the ticket CSV into the workbook (Power Query or paste), count tickets per customer, then look them up against the renewals table. In Analistable you load both files and ask the question; the SQL is a join plus a HAVING COUNT(*) > 3 filter. Either way, check that customer names match exactly; a fuzzy name mismatch drops rows silently. See matching support tickets to customer accounts for that clean-up.

Choosing between them

1. Your data is in one workbook and you have a Copilot licence: use Copilot.
2. You need the result as formulas or formatting in the file: use Copilot or plain Excel.
3. The question spans files, Google Sheets or GA4, or you have no Copilot licence: use Analistable.
4. You want a reviewable SQL answer that re-runs on next month's files: Analistable.

They are not exclusive. Many teams use Copilot day to day and reach for a cross-file tool when a question crosses a departmental boundary, such as finance data meeting support or marketing data that nobody wants to paste into a shared workbook.

Frequently asked questions

Is Copilot in Excel free?

Not generally. It requires a Microsoft 365 plan that includes Copilot or a Copilot add-on licence. Terms differ for business and consumer plans and change over time, so confirm with your administrator or Microsoft's plan pages.

Can Copilot analyse two workbooks at once?

It works on the workbook you have open. To combine data from other files, bring them into that workbook first, for example with Power Query.

Does Analistable edit my Excel file?

No. It reads the file into a browser database and answers questions; your original workbook is unchanged.

Do I need Copilot if I already use Power Query?

Not for combining data: Power Query does the joining and appending. Copilot helps afterwards with formulas, formatting, charts and summaries on the combined table, so the two complement each other.

Can Analistable read a workbook stored in OneDrive?

Yes. Connect your Microsoft account and pick the workbook from OneDrive or SharePoint; Analistable gets read-only access, loads the data into your browser and never writes back to the file. You can also load Excel and CSV files from your device, or Google Sheets through its connector.

Which is better for formula help?

Copilot, because it works directly in the grid and writes Excel formulas. Analistable answers with SQL rather than Excel formulas.
