Claude in Excel: Your AI Spreadsheet Analyst

June 21, 2026 · Braintek

Reviewing business data and reports

If you spend hours in Excel — and have ever lost 20 minutes hunting for one broken formula — this is for you. Claude now works right inside Excel, in a sidebar that can read your whole workbook and actually help.

Ask it in plain English and it will find and explain a broken formula, analyze data across multiple tabs, build a formula or chart for you, clean up a messy CSV, or summarize a P&L. It’s less “AI chatbot” and more “a sharp analyst sitting next to you.”

One rule that matters: don’t paste confidential or regulated data into a consumer AI tool. The business tiers add real data protection — and setting that up safely is something we help with.
