Is There a Copilot Add-in for Excel? No Download in Microsoft's Setup, but 3 Add-ins You May Be Offered
The short answer: for Copilot in Excel itself, Microsoft's setup steps contain no download, install or add-in step. You open Copilot with the button in the lower-right corner of Excel. You need a licence and current Microsoft 365 Apps.
Add-ins do exist around it, and that's where the confusion starts. Microsoft publishes 2 related ones (Finance Agent and Excel Labs), and third-party add-ins borrow the Copilot name. Here's which is which, and how admins approve them.
Copilot add-in for Excel: what Microsoft's setup pages actually say
Microsoft's instruction for opening Copilot in Excel is 1 sentence: "Select the Copilot icon in the lower-right corner of Excel." A text search of 12 Microsoft support pages on Copilot in Excel (8 November 2026) finds no download, install or add-in step. Not one.
I'd love to hand you a Microsoft quote saying "built in, no add-in needed". None of the pages checked says it, so I won't invent one. What the pages do list is the plumbing: Microsoft 365 Apps that are deployed and current, an eligible licence, and the network and privacy settings. If the button still isn't there, that's a different problem, and Copilot not showing in Excel covers it.
Admins get one more clue. Microsoft's FAQ says Copilot in Excel "is a Microsoft Copilot Chat tool and can't be turned off independently". Microsoft says the Copilot Chat admin settings apply, so there is no separate switch for Copilot in Excel.
The 3 add-ins you may be offered, and who publishes each
| Add-in | Publisher | What it is | Is it how you get Copilot in Excel? |
|---|---|---|---|
| Finance Agent (for use in Excel) | Microsoft Corporation | AI assistant for finance tasks. Formerly Copilot for Finance. | No |
| Excel Labs | Microsoft Corporation (a Microsoft Garage project) | Experimental features, labelled previews. | No |
| "Copilot for Excel Spreadsheet" | Standards Core, a third party | A Marketplace add-in with Copilot in its name. | No, and not Microsoft's |
1Finance Agent (for use in Excel)
Microsoft renamed Copilot for Finance, and its pages now also say Finance in Microsoft Copilot (pick one, Microsoft). It targets finance work such as data cleansing, reconciliation and variance analysis. Business users can install it from Marketplace and admins can deploy it. Microsoft says it can take up to 6 hours to appear in Excel. It may need an extra licence, free or paid. The interface is currently US English only, and the reconciliation documentation is still labelled prerelease.
2Excel Labs
Microsoft's launch post says the =COPILOT function succeeded an experiment that debuted in Excel Labs. Here's the catch: the listing still says Excel has an in-the-box =COPILOT function, and Microsoft retired it on 14 September 2026 (the retirement story). So the listing is stale. It also says the add-in can read and make changes to your document and can send data over the internet. Does the old experiment still work? Microsoft doesn't say.
3The third-party look-alike
A name collision. The listing in the table sits on Marketplace too, but the publisher is Standards Core, not Microsoft. This page doesn't vet it or recommend it. A third-party add-in brings its own vendor and its own terms, so it should go past your admin before anyone installs it.
One I couldn't find: a Microsoft add-in actually named "Copilot for Excel". No Microsoft add-in with that name turned up in the searches done for this article. That isn't proof it doesn't exist. Marketplace search is built with scripts a plain text check can't read, so look at the publisher line yourself. (I have no commercial interest in Microsoft or in any add-in vendor.)
For IT: how to approve, pilot or block an add-in, in 5 steps
Steps 1 to 4 follow Microsoft's own admin documentation for Office add-ins. Step 5 is my addition.
1Deploy centrally with Integrated apps
Microsoft calls the integrated apps portal "the recommended and most feature-rich way for most customers" to deploy Office add-ins centrally. Here's the click path. In the Microsoft 365 admin center, go to Settings > Integrated apps, select the Add-ins link near the top, then Deploy Add-in.
2Pilot with a small group
Microsoft's advice: a small set of business stakeholders and IT first, then wider. You can assign an add-in to everyone, to specific users or groups, or just to yourself, and Microsoft recommends groups. And be patient. Microsoft says Office add-ins can take 24 to 72 hours to appear, so don't announce one in the morning and expect it on everyone's screen by lunch.
3Decide whether staff can install their own
To block user-initiated downloads, go to Settings > Org settings > Services > User owned apps and services and clear "Let users access the Office Store". (The admin center sometimes calls Microsoft Marketplace the Office Store. Same shop, 2 names.) Staff then see a message that your organisation has disabled access.
4Remember that add-ins from Marketplace update automatically
Microsoft says add-ins deployed from Marketplace get updates and enhancements automatically. The add-in's permissions stay the same. The web application behind it, though, can change at any time, Microsoft notes.
5Check 4 things before you approve
This is my checklist, not Microsoft's: the publisher, what the add-in can read, change and send out (the Excel Labs listing spells this out), whether it works in your language, and what licence or fee comes with it.
For the colleague who asks, here is a reply you can paste. The wider IT questions are in my Copilot readiness checklist, and the IT pre-flight checklist covers a workshop day.
You don't need to install an add-in to use Copilot in Excel. Microsoft's setup is the Copilot button in the lower-right corner of Excel, plus a licence and up-to-date Microsoft 365 apps. Can't see the button? Tell me and I'll check with IT. Please check with IT before you install any add-in with Copilot in the name from the store, because some are third-party.
4 claims about Copilot add-ins to stop repeating
1"Microsoft says it's built in, no add-in needed"
None of the pages checked uses those words. The accurate version is narrower. The setup steps contain no download.
2"There is no Microsoft add-in"
Finance Agent (for use in Excel) and Excel Labs are both on Marketplace under Microsoft Corporation.
3"Finance Agent or Excel Labs is how you get Copilot"
Neither is. Finance Agent is a finance product, and the Excel Labs listing still describes the retired =COPILOT function as built in.
4"If Marketplace says Copilot, it's Microsoft's"
Read the publisher line before anyone clicks.
Questions about the Copilot add-in for Excel
Is there a Copilot add-in for Excel?
Not for Copilot in Excel itself: Microsoft's setup steps contain no download or add-in. Microsoft does publish 2 related add-ins, Finance Agent (for use in Excel) and Excel Labs. No Microsoft add-in named Copilot for Excel turned up in the searches done for this page.
Do I need to download anything to use Copilot in Excel?
Microsoft's setup pages list no download. You open Copilot with the button in the lower-right corner of Excel. You do need an eligible licence and Microsoft 365 Apps that are deployed and current.
How do I add Copilot to Excel?
Microsoft's setup has no add-in step. Select the Copilot icon in the lower-right corner of Excel. If the icon isn't there, work through the checks in Copilot not showing in Excel.
What is Finance Agent in Excel, and is it Copilot for Finance?
Finance Agent (for use in Excel) is Microsoft's add-in for finance tasks such as reconciliation. It is the renamed Copilot for Finance, and Microsoft's pages also call it Finance in Microsoft Copilot. It is a separate product, with a US English interface only.
Is Excel Labs the Copilot add-in?
No. Excel Labs is a Microsoft Garage project for experimental features. Microsoft retired the =COPILOT function on 14 September 2026, and the Excel Labs listing still describes it as built in.
Can my admin block add-ins like Copilot for Excel?
Add-ins, yes. Clear Let users access the Office Store under Org settings and deploy only through Integrated apps. Copilot in Excel itself isn't an add-in, and Microsoft says it can't be turned off independently of Copilot Chat.
Fewer download links, more people actually using Copilot.
I run live online Copilot workshops, hands-on, from 1.5 to 4 hours, for groups of 20 to 25 at most. Clients include Intel, Roche, EY, Deloitte and Amdocs.
