Claude for Office

What it is

Microsoft Office add-ins that put Claude inside Excel, PowerPoint, and Word as a task-pane agent. Ask questions about the document you’re in, update cells or slides, debug formulas, draft or revise copy, and hand work between apps — all with cell-, slide-, and paragraph-level citations back to your source content.

In beta. Available on Pro, Max, Team, and Enterprise plans.

Where to find it

Excel

• Desktop or web → Home → Add-ins → find Claude → Add.
• Opens in the right-hand task pane.

PowerPoint

• Desktop or web → Home → Add-ins → find Claude → Add.
• Task pane appears on the right.

Word

• Desktop or web → Home → Add-ins → find Claude → Add.
• Task pane opens alongside the document.

Sign in with your Claude account when the pane first loads. Team/Enterprise admins may need to approve the add-in through the Microsoft 365 admin center before users can install.

How to use it

Excel

1. Open a workbook and launch the Claude pane.
2. Ask about a sheet: “What drives the variance in row 42?” or “Fill this template from last quarter’s actuals.”
3. Claude returns answers with cell-level citations you can click to jump to.
4. Approve changes before Claude writes to the workbook. Formula dependencies are preserved when assumptions change.
5. Use it to debug #REF! / #VALUE!, build models from scratch, or fill structured templates.

PowerPoint

1. Open a deck and launch the pane.
2. Ask Claude to draft slides, rewrite existing ones, or restructure a section.
3. Claude can generate speaker notes, tidy layout, and match existing slide templates.
4. Review slide-level diffs before accepting.

Word

1. Open a document and launch the pane.
2. Ask for a draft, a rewrite, a summary, or targeted edits.
3. Claude works with selections or the whole document, citing paragraphs.
4. Accept or reject changes inline.

Good to know

• Dictation in Office agents — every add-in supports voice input. Tap the microphone in the pane to speak your prompt; audio is transcribed and discarded.
• Work across apps. Claude can move context between Excel, PowerPoint, and Word — pull numbers from a workbook into a deck, or turn a Word brief into slides — within a single session.
• Third-party platforms. The same add-ins work against Google Workspace files (Sheets, Slides, Docs) and other compatible platforms, so you’re not locked into Microsoft 365.
• Availability. Pro, Max, Team, Enterprise. Free and regular consumer plans do not include Office add-ins.
• Usage counts toward your Claude plan — Office turns draw from the same pool as chat and Claude Code.
• Admin install. Enterprise admins can push the add-in via Microsoft 365 centralized deployment. Check with your admin if “Add” doesn’t appear.
• Citations are the safety rail. Every material claim Claude makes about your file points back to the specific cell, slide, or paragraph — review before accepting.
