Claude in Excel is here

Claude in Excel is out in beta and it’s pretty wild what it can do.

The core idea is that Claude can actually understand your entire workbook, not just one cell at a time. It sees nested formulas, dependencies across multiple tabs, and how calculations flow through your model. So when you ask it something, it gives you explanations with cell level citations so you can actually verify the logic yourself.

A few things that stand out to me. First, you can test different scenarios and update assumptions across your whole model without breaking any formulas. Claude highlights every change and explains what it did. Second, debugging errors like #REF or #VALUE or circular references becomes way faster because it can trace the problem back to the source and tell you how to fix it. Third, you can build draft financial models from scratch or populate existing templates with new data while keeping all the structure intact.

You open it with Control Option C on Mac or Control Alt C on Windows. It’s available for Max, Team, and Enterprise plan customers right now.

What’s the first thing you’d want to try with this? I’m curious if people are more excited about the debugging side of things or the scenario testing where you can play with assumptions and see the downstream impact.​​​​​​​​​​​​​​​​
