Why choose GPT for Work over ChatGPT, Copilot, or Gemini?

You've figured out a great prompt in ChatGPT, and now you want to apply it at scale to thousands of items in your spreadsheet.
Microsoft Copilot and Gemini for Workspace don't support bulk AI processing. ChatGPT agent mode doesn't either.
GPT for Work is the only "ChatGPT at scale" product for Google Sheets and Microsoft Excel.
