Claude for Microsoft 365

Claude for Microsoft 365 brings Claude into the apps you already work in. Update assumptions in Excel without breaking formulas, restructure a deck in PowerPoint using your slide master, and redline contracts in Word with tracked changes — all from a sidebar chat that carries context across apps.

In Excel, Claude reads multi-tab workbooks, builds models with real formulas, and tracks every cell it changes. In PowerPoint, it works inside your template — your layouts, your fonts, your colors — and produces native charts you can edit. In Word, edits land as a tracked change, and Claude responds to comment threads with what it changed and why.

Claude for Microsoft 365 is generally available on all paid Claude plans.
