FAQ

We recommend Claude in Excel first. Open a multi-tab workbook left by a predecessor and have it explain the assumptions and calculation flow. Follow the cell citations to verify.

  • Microsoft Copilot (spotting odd values in Excel tables): With a sales or expense table open, ask about “rows that don’t add up” and it points out what you missed by eye. Always verify results against the original formulas.
  • Claude Code (merging scattered Excel files): Have it pull several files with mismatched formats into a single sheet, and flag missing values and totals that don’t add up. A person only checks the flagged spots.
  • Claude in Excel: The add-in itself is free to install, but you need a paid Claude account to use it. It is available on Pro, Max, Team, and Enterprise plans.
  • Microsoft Copilot: You can chat with it for free in the Copilot app and on the web. However, features inside work documents such as Word and Excel require a paid Microsoft 365 plan or an enterprise license.
  • Claude Code: The official documentation states that the free claude.ai plan does not include Claude Code. You need a Pro or higher plan, or a Console (API) account.
