If your business has Microsoft 365 Copilot licenses, something changed in Word, Excel, and PowerPoint last week. It’s worth a few minutes of your time.

What actually changed

Until now, Copilot in Office apps was mostly a suggestion engine. You’d ask it to restructure a document and it would describe what to do, or spit text into a side panel for you to copy-paste. Useful sometimes. Underwhelming often.

The April 22 update changes that. Copilot now works directly inside your documents, spreadsheets, and presentations. Microsoft calls this “agentic,” which is their word for “it takes action instead of talking about it.” Ask Copilot to reorganize a report, and it reorganizes the report. Ask it to build a chart from your data, and it builds the chart. In the document. Not in a sidebar.

You still have full control. Every change is reviewable and undoable, and you can set preferences around style and formatting that Copilot will respect. But the dynamic is different now: Copilot does the work, you review it.

What this looks like in practice

In Word, Copilot edits your document directly. Change the tone of a section, condense a 10-page report into an executive summary, restructure a proposal. It happens in the document, not in a chat window you have to copy from.

Excel got the biggest improvement. Copilot can build formulas, create pivot tables, and generate charts inside your workbook. You can ask a plain-English question like “what drove the change in revenue last quarter” and get an actual analysis with visuals, not a paragraph explaining what you could try. Microsoft says Excel Copilot engagement jumped 67% after the update, which tracks with what I hear from clients who found the old version frustrating.

In PowerPoint, you can update existing decks with new talking points and data while keeping your company’s templates intact. If you’re refreshing a quarterly presentation, you describe what changed and Copilot makes the edits across your slides.

Who gets this

Anyone with a Microsoft 365 Copilot add-on license. It also works on the consumer Personal, Family, and Premium plans. If your organization is on M365 Business Standard or Business Premium without the Copilot add-on, you won’t see these features. The update rolled out automatically for licensed users. No admin action needed.

If your firm has Copilot licenses and nobody’s touched them in a while, this is a good reason to take another look. I’ve talked to several firms that wrote Copilot off after the initial launch because the experience felt clunky. This update addresses the most common complaint: that Copilot talked about helping more than it actually helped.

A few things to think about first

More autonomy from the tool means more governance on your end.

Copilot works with whatever data your users can access, and now it’s doing more with that data without asking. If your SharePoint permissions and file structure aren’t cleaned up, Copilot could pull from documents your team didn’t mean to reference. That was true before, but it matters more when the tool is making edits rather than suggestions.

If your organization has an AI acceptable use policy, check whether it covers autonomous actions. There’s a real difference between someone asking Copilot “summarize this document” and Copilot restructuring a report on its own. Your policy should say where that line is.

If your business handles sensitive client information, think about whether this changes your disclosure obligations. “We use AI to suggest edits” and “we use AI that makes edits to your documents” are different statements. Your clients or regulators may have opinions about that distinction.

One more thing: Microsoft’s announcement specifically mentioned “deeper, more reliable editing for complex workflows” with legal documents and finance spreadsheets as the next priority. If your business runs on documents and data, Microsoft is building this with you in mind.

The bottom line

This update doesn’t come with a new license or a new app name, so it’s easy to miss. But Copilot going from “suggests things in a sidebar” to “makes changes in your document” is a real shift in how the tool works. If your team tried it early and walked away unimpressed, it’s worth another look.
