    Run an Online Repair of Microsoft 365 or Office, which repairs the entire Office installation when Excel reports that it cannot work correctly and needs repair.^1^

    1. Repair Microsoft 365 or Office

    Save your work and close all Office applications first.

    Windows 11

    1. Right-click Start and select Installed apps.
    2. Find Microsoft 365, Microsoft Office, or your standalone Excel installation.
    3. Select the three dots beside it, and then select Modify.
    4. For a Click-to-Run installation, select Online Repair → Repair.
      • If the window only offers Repair and Continue, select those options; this indicates an MSI-based installation.
    5. Follow the prompts, restart the computer when complete, and open Excel.

    Windows 10

    1. Right-click Start and select Apps and Features.
    2. Select Microsoft 365 or Microsoft Office, and then select Modify.
    3. Select Online Repair → Repair and complete the prompts.
    4. Restart Windows and test Excel.

    Online Repair is more thorough than Quick Repair. It can require an Internet connection and will repair the entire Office suite, even when only Excel is affected.^1^

    2. If Excel still fails, test Safe Mode

    Safe Mode starts Excel without most add-ins and customized startup settings:

    1. Press Windows key + R.
    2. Enter:
    excel /safe
    1. Select OK.
    2. If Excel opens, select File → Options → Add-ins.
    3. At the bottom, set Manage to COM Add-ins, and select Go.
    4. Clear every checkbox, select OK, close Excel, and start it normally.
    5. If Excel now works, enable the add-ins individually, restarting Excel after each one, to identify the conflicting add-in.^2^

    If Excel does not open in Safe Mode, the problem is less likely to be a COM add-in.

    3. If Online Repair does not restore Excel

    Uninstall and reinstall Microsoft 365 or Office. Microsoft provides an uninstall troubleshooter for Microsoft 365 and Office 2021, 2019, and 2016; it must run on the affected Windows PC, and it requires Windows 10 or later. After uninstalling, restart the computer and reinstall the edition associated with your Microsoft account.^3^

    If this is an organization-managed computer, contact the IT administrator before uninstalling because installation and activation may be centrally controlled.

    Hi, @Adjudi cation

    Sorry you're dealing with this, it's frustrating when Excel won't even open. Since the repair and add-in steps have already been suggested, here are a few other things worth trying.

    First, does the error pop up only when you double-click a specific file, or also when you open Excel by itself from the Start menu? If it's just one file, open Excel first, then go to File > Open > Browse, click the small arrow next to the Open button and choose Open and Repair. That handles a damaged workbook rather than a broken Excel.

    If Excel itself won't start, try these:

    Open Word or another Office app, go to File > Account > Update Options > Update Now. A pending update sometimes fixes this.

    Press Windows + R, type %appdata%\Microsoft\Excel\XLSTART and hit Enter. Move anything in that folder to your Desktop, then try Excel again. Excel loads whatever is in there on startup, so one bad file can block it.

    Run the Excel troubleshooter in the Get Help app, which checks startup files and toolbar settings automatically: Excel not responding, hangs, freezes or stops working

    Check that your license is still active at https://account.microsoft.com/services. If it's there, open Word, go to File > Account, sign out, restart the PC and sign back in.

    Let me know what you see after these and I'll help narrow it down further.
