I run the Excel team at Microsoft. The experience you're describing sounds like it's from the earlier versions of Copilot in Excel that were genuinely limited.

Today, Excel Copilot takes a model-forward approach where we give the models full access to Excel's capabilities. We give customers the choice of the latest models from both OpenAI and Anthropic, and we encourage the models to iteratively explore the spreadsheet before taking action. It builds a full understanding of the semantics and structure of the spreadsheet, find issues in it, and ultimately gives you much better results.

Copilot can write formulas, build PivotTables, create charts, build multi-tab models, do multi-step analysis. The models are quite proficient at it, and they do a great job. We have an auto-mode which is the default where we pick the model for you, but you can also select specific models if you have a preference. I often see people switch between models to get the benefit of diverse perspectives, similar to how a diverse team approaches problems differently.

If you tried it a few months ago and walked away, it's worth another look.


Does Copilot behave differently in Excel depending on whether you got the premium subscription instead of what is included with Business?

Many people I've talked to about Copilot don't realize that the dedicated "Premium" Copilot is a completely different experience than the "Basic/Lobotomized" Copilot that comes with a standard Business subscription.

It's like you're running a freemium model where no one was actually responsible for implementing the upsell, or making sure the free version is useful and compelling. E.g. a Copilot pane in Outlook that says it can't access your emails, doesn't explain how, and doesn't mention an upgrade path that will allow it to.


Current model is inauthentically limited?

"If you tried it a few months ago and walked away, it's worth another look." You shouldn't have shoved trash down people's throats a few months ago then?

While I agree the widespread "race to market" with crap probably does and should hurt the success of these "AI-enabled apps," that particular area probably was not this individuals decision.


It was this person's decision to mention their senior role at MS then dump marketing drivel into our heads. It's not his hand but he still eats with it.


I've had a really good time with the new Copilot in Excel. I like the model selector and tend to use Opus 4.6.

Q for you Brian, I have the Microsoft 365 Premium individual plan ($200/yr). I got 50% off the premium plan as well when Microsoft was offering discounts.

I've noticed when I use Claude or GPT through the Copilot model selector I don't see any costs for my api usage anywhere. Does Microsoft eat that for now?


Glad you're enjoying it! Opus 4.6 is great, and we've started rolling out 4.7 today.

Your M365 Copilot Premium plan includes extensive usage of the Copilot features, including the model selector, and there are no additional API costs.


Thanks for clarifying this. I was genuinely frustrated with copilot due to the lack of features.

If it's possible please push your large business clients to update office. I work for a multinational pharma company and the copilot feature in excel deployed there is next to useless


just tried it: i can't even use CSV files with Copilot...

Without coming across as overly rude, it is frankly astonishing how limited Copilot is.

I do not like being an MS customer or user.
