Frequently asked questions
Do I need Microsoft Copilot to use this Excel tool?
No. You can generate the prompt here and paste it into ChatGPT, Claude, Gemini or Copilot. Copilot adds live access to your Excel file, which is convenient but optional.
Will the AI change my original file?
No. FormelyAI only generates text prompts. You copy the result and apply it yourself, so you stay in control of your documents.
