Which AI add-ins work inside Excel?
Last verified 2026-10-31In editorial reviewPaid placement never changes our picks.
Short answer
As of October 2026, start with Microsoft Copilot if you already pay for Microsoft 365, ChatGPT for Excel if you want an add-in that works on every ChatGPT plan, and Autosheet if you need one prompt run across thousands of cells. The catch: these agents edit live workbooks, so keep a copy and check changed formulas.

Works in Excel and Google Sheets without an API key. No prices are published on its site.
Prices come from each tool's fact block. "See pricing page" means we have not confirmed the number on the official pricing page in the last 30 days, so we do not show one.
How to choose
- If you already have Microsoft 365 Personal, Family or Premium → use Copilot, which is built into Excel (Personal is $9.99 a month on Microsoft's page).
- If you already use ChatGPT or Claude → install that vendor's add-in (ChatGPT for Excel is on all ChatGPT plans; Claude for Excel needs a paid Claude plan).
- If you need AI formulas over many rows → Autosheet or Numerous.ai (both add AI functions to cells; Autosheet's plan covers either Excel or Sheets, not both).
- If you build finance models → Shortcut (Excel plugin plus its own web and desktop app; the vendor states SOC 2 Type II).
- If your company restricts data → check admin rules first (Claude's docs say its Excel add-in does not inherit custom retention settings or appear in Enterprise audit logs).

Where sources disagree
- Fairness disclosure: Claude is built by Anthropic, the maker of the model that drafted this page; held to the same standard. Anthropic rows use the same fields and plain wording as the others, and ranks follow the reader's situation, not preference. Claude for Excel ranks below ChatGPT for Excel because it needs a paid plan.
- ChatGPT plan prices: chatgpt.com/pricing showed plan names but no amounts to our browser; availability on all plans comes from OpenAI's own launch post, updated May 5, 2026.
- Renamed tools: GPT for Work is now Autosheet, and Formula Bot is now Better Analyst, a web analysis app that no longer presents an Excel add-in, so it is not a pick.
- Vendor benchmark: Shortcut's homepage compares its cost per finance task with Claude for Excel; that is the vendor's own evaluation, not an independent test.
