We're sorry, but Excel has run into an error that is preventing it from working correctly. Excel will need to be closed as a result. Would you like us to repair now?

    Hi, I'm Bernard. I'm happy to help!

    Kindly follow the steps provided by the AI answer. However, if the issue persists, I recommend reinstalling the Office app by following the steps below:

    Press the Windows key + R, then type in:

     

    appwiz.cpl

     

    Then hit OK

     

    Look for the Microsoft Office or Microsoft 365 app > Right-click, then select Uninstall

    Follow the prompts to uninstall your Office app.

    Then reinstall your Office app by following the steps from the link below:

    Use the following steps in order until Excel works normally again:

    1. Close all Office apps (Excel, Word, Outlook, etc.).
    2. Run an Online Repair of Office:
      • Open Settings in Windows.
      • Go to Apps → Installed apps.
      • Find Microsoft 365 (or Office) in the list.
      • Select the three dots (…) → Modify.
      • Choose Online Repair and confirm.
      • Let the repair complete (this can take 15–30 minutes) and do not cancel it.
      • Restart the PC when the repair finishes.
      • Open Excel and check if it starts and works without the error.

    If the error appears in all Office apps and Online Repair does not resolve it, completely remove and reinstall Office:

    1. Uninstall Office from Apps & Features (or Programs and Features).
    2. Manually delete any remaining Office folders in the locations indicated in the existing guidance that was followed.
    3. Carefully clean remaining Office-related registry keys (only if comfortable editing the registry), then restart the computer.
    4. Reinstall Microsoft 365/Office and sign in with the Microsoft account or work/school account that holds the license.

    If Excel still fails after these steps, check for third‑party add‑ins (such as PDF or other integration add‑ins) that may be interfering and disable or remove them, then test Excel again.
