Anthropic just fixed Microsoft Office: Claude finally syncs Excel & PowerPoint together seamlessly, and you can now analyze data in one and generate slides in the other with full context 😳

No copy-paste.

No re-explaining the dataset.

No losing context when switching apps.

Just one continuous workflow.

Claude’s new Excel and PowerPoint add-ins now share context across files.

Meaning the AI remembers what’s happening in your spreadsheet while it edits your slides.

The demo below shows Claude’s real power:

→ Analyze portfolio data in Excel

→ Build a comps table and valuation summary

→ Drop it straight into a PowerPoint deck

→ Update slides automatically when the spreadsheet changes

All inside one conversation.

Then Anthropic added something even more interesting: Skills.

Think of them as one-click workflows for common work.

Examples:

→ Audit a financial model

→ Clean messy spreadsheets

→ Generate comps tables

→ Turn analysis into client-ready slides

Companies can also create their own.

Meaning internal playbooks like:

- “How we run LBO models”

- “How our firm formats decks”

- “How we do variance analysis”

can become reusable actions shared across the whole organization.

Claude is now available across:

- Excel + PowerPoint add-ins (Mac & Windows)

- Amazon Bedrock

- Google Vertex AI

- Microsoft Foundry

Which leads me to believe that Anthropic might end up automating Microsoft Office better than Microsoft itself.

Most importantly, the biggest shift here is not about a better chatbot.

It’s that the chatbot window is disappearing.

AI is becoming the reasoning layer inside the tools where work actually happens.
