Troubleshooting
I don't see Add-ins

- Make sure your Excel/PowerPoint is updated.
- Confirm you're signed in to your account.
ChatGPT installed but won't open
- Close Excel/PowerPoint completely and reopen.
- Open a workbook and try the same steps to open.
Can't sign into Chat in Application
- Make sure your Excel/PowerPoint and Chat are logged in to the same account
- Ex: Your Excel is Cedarville but Chat signed into your personal account.
Other General Tips
- If ChatGPT isn't listed, suspect a Microsoft 365/organization restriction.
- If ChatGPT is listed but won't open, test PowerPoint for the web.
- If it opens but won't sign in, check the ChatGPT account and SSO.
- If you get "This add-in could not be started," involve your Microsoft/OpenAI administrator and have them check the organization's SSO configuration.
Excel-Specific
Chat doesn't understand my workbook
- Be explicit and detailed in your prompts.
- (E.g. Analyze the "January Data" sheet only. Do not modify anything. Explain the formulas in columns H through M.)
- For changes: Update the formulas in column M to use the values in column L. Do not change formatting or any other cells.
PowerPoint-Specific
Chat can't edit my presentation
- Start simple. (E.g. βββββββAnalyze this presentation and tell me what you can change.)
- Gradually ask more. (E.g. Add one title slide. Do not change any existing slides.)
- For large edits, ask for a plan. (E.g. Before editing the deck, tell me which slides you would change and why. Do not make changes yet.)
The formatting doesn't match my template
- Use prompts like the following for creation:
- Match the existing deck's fonts, spacing, title treatment, colors, and layout conventions. Do not introduce a new visual style.
- For specific slides:
- Use slide 4 as the visual reference. Create the new slide using the same layout, typography, spacing, and formatting.
