@keith.rainville: Don't trust a total in your spreadsheet? Claude for Excel can walk you through how a number was derived 👇 📥 Grid 1: Add Claude for Excel from Microsoft AppSource, open Excel, activate the add-in and sign in with your Claude account 📋 Grid 2: Start with a trusted copy of the workbook, as Anthropic's best practices page says 🔎 Grid 3: Ask how a number was derived: the answers include cell-level citations you can click 🧭 Grid 4: Ask it to find the source of an error, like the #REF! example on the page ✅ Grid 5: Change one assumption, then review every change before you finalize your work The catch: Anthropic's docs page says Claude for Excel is not recommended for final client deliverables without human review, and to only use it with trusted spreadsheets because files from external sources can contain hidden instructions.
