Hi. When we're trying to embed onedrive excel sheets' url on the website to provide problems in order to practice MS Excel formulas, it's showing no sheet/blank sheet. We've check embedded code, it's perfectly right for all problems. We're doing this all for our platform excelpractice.online with 2,00,000+ Users using it and now it's impacting our core offering of the product. Kindly look into it at the earliest.

Thanks, Achalesh.

    Hi Achalesh,

    Good day. Thank you for sharing the details of the issue and the browser console screenshot. 

    I appreciate you confirming that the troubleshooting steps suggested by the AI response did not resolve the problem. 

    As this is a user-to-user community forum, I do not have the ability to directly access or modify your account or service. However, I can provide guidance, recommend next steps, share applicable resources, and direct you to the appropriate support channels so the issue can be investigated further.    

    Based on the console information provided, the embedded OneDrive/Excel viewer appears to be failing while loading the following Microsoft-hosted JavaScript dependency: 

    odsp.react.lib-f74dfea2.js 

    HTTP 404 (Not Found) 

    Uncaught Error: Script error for "odsp.react.lib" 

    This missing dependency prevents the OneDrive embedded viewer from completing its initialization, which can cause the workbook area to appear blank. Therefore, the behavior does not appear to be caused by the iframe syntax or workbook configuration on your website. 

    I have also recently seen a few other users report similar behavior involving blank OneDrive embedded content and the same Microsoft CDN script-loading error. Based on the available evidence, this appears more consistent with a possible service-side or CDN deployment issue affecting the OneDrive embedded viewer. 

    In the meantime, as a temporary workaround, you may consider: 

    • Providing an Open in Excel for the web or Open in a new tab link for each workbook. 
    • Allowing users to download the workbook where appropriate. 
    • Displaying a temporary notice explaining that the embedded Excel viewer is currently unavailable. 
    • Avoiding mass regeneration of existing embed URLs, as newly generated URLs may still depend on the same unavailable Microsoft resource. 

    Since this issue is impacting your core service, please contact your school or organization’s IT administrator and ask them to report the issue through: 

    Microsoft 365 admin center > Health > Service health > Report an issue 

    When submitting the report, the administrator should include the following information: 

    • An affected embed URL or a non-sensitive reproducible example. 
    • The exact time the issue was reproduced, including the time zone. 
    • The browser console screenshot and, if possible, a HAR/network trace. 
    • The failed Microsoft CDN request for odsp.react.lib-f74dfea2.js. 
    • Confirmation that the issue affects multiple embedded workbooks. 
    • The business impact, including that the issue is affecting the core functionality of a platform serving more than 200,000 users. 

    Reporting the issue through Service health will help Microsoft identify its scope and correlate the report with similar cases from other affected customers. 

    If needed, the Microsoft 365 administrator can also open a support ticket with Microsoft Support through the Microsoft 365 Admin center > Help & support so that the tenant information, network trace, and affected embed requests can be reviewed in greater detail. 

    I hope this information is helpful. Should you have any further questions or need additional assistance, please feel free to share them in the comment below. I'm very happy to help.

    For embedded OneDrive Excel files showing a blank sheet, use this recovery path:

    1. Regenerate the embed HTML from OneDrive.
      • Sign in at onedrive.com.
      • Go to Files and locate the workbook.
      • Select the file, choose </> Embed, then select Generate.
      • Replace the old iframe HTML on the website with the newly generated code.
      • If the embedded file no longer shows, Microsoft states the file may no longer be available or the link used has changed.
    2. Verify the embed is using supported format.
      • The embed code must be iframe-based.
      • If any embed implementation uses script tags, it is not supported.
      • If embedding through a SharePoint page or similar host, only HTTPS sites are supported.
    3. Test the workbook anonymously.
      • Open a browser in private/incognito mode.
      • Open the page containing the embedded workbook.
      • Confirm the workbook loads for an unauthenticated viewer.
      • This checks whether the file owner has access that public viewers do not.
    4. Check for browser cookie/cache issues.
      • A reported case of embed URLs suddenly failing was resolved by deleting browser cookies.
      • Test in an incognito/private window first. If it works there, clear cookies for the affected browser session and test again.
    5. If the workbook was embedded from SharePoint or OneDrive for Business, regenerate the embed code from Excel for the web.
      • Upload or open the workbook in the document library.
      • Open the Excel file in the browser.
      • Go to File > Share > Embed.
      • Generate fresh embed code and replace the existing iframe.
      • For Excel files, a generic file iframe may not work; generating the embed code from the Excel workbook is the documented working path in the provided guidance.
    6. Review workbook and traffic limits.
      • Embedded workbook size limit: 10 MB.
      • Concurrent viewers limit: 1000.
      • Heavy traffic can cause some viewers to be throttled, and availability can be affected by the number of embedded workbooks in the data center or tenant.
    7. If the workbook loads but presentation is wrong, review iframe parameters.
      • Parameters such as Item, ActiveCell, wdHideSheetTabs, and wdAllowInteractivity affect what is shown.
      • An incorrect Item or saved view can make the embedded result appear blank or not show the expected range.

    Most likely fixes from the available guidance are:

    • regenerate the embed code,
    • test in incognito/private mode,
    • clear browser cookies,
    • and ensure the workbook was embedded using Excel’s own Embed flow rather than a generic file link.
    AI-generated content may be incorrect. Read our transparency notes for more information.
