Spreadsheets are no longer silent grids of numbers. Claude AI has moved in, and it's bringing a conversational, reasoning layer to one of the world's most essential business tools. Welcome to a world where you don't just build a financial model—you talk to it.

Imagine highlighting a complex, nested formula and simply asking, “What does this do?” Instead of reverse-engineering the logic cell by cell, Claude instantly explains the calculation flow across tabs, complete with citations. Stuck on a #REF! error? Claude traces it to the source in seconds, acting like a forensic detective for your data.

This isn't just about explanation—it's about intelligent iteration. Want to test a new business scenario? Tell Claude your new assumption. It updates the entire model, preserving every formula and dependency, and shows you exactly what changed and why. It can even build draft models from your description or intelligently populate existing templates.

The beta is available now, bringing the trusted Claude experience directly into the Excel interface. For anyone who's ever wrestled with a multi-tab monster of a spreadsheet, this isn't just an upgrade—it feels like the tool has finally gained a mind of its own.
