Excel Mobile App for iPad Suddenly Freezing, Failing to Save, and Becoming Unresponsive Across 22+ Devices

We have approximately 22 service technicians who use the Microsoft Excel mobile app on iPads every day to complete inspection reports in the field. This workflow has worked reliably for years.

However, within the span of approximately one day, all of our technicians began experiencing severe performance and reliability issues with Excel for iPad.

The issues include:

  • Excel taking an extremely long time to save files or failing to save altogether.
  • The app freezing or becoming unresponsive when attempting to Save a Copy.
  • Files occasionally failing to save changes.
  • The on-screen keyboard sometimes failing to appear when selecting a cell.
  • General freezing, lagging, and instability that has made Excel effectively unusable for our field technicians.

What is particularly unusual is that this began affecting essentially all of our technicians at approximately the same time.

We have a wide variety of iPads in service, including 8th, 9th, 10th, and 11th-generation models, newer M4 iPads, and iPad Air models with different storage capacities. The same problems are occurring across all of them.

The devices are also running a variety of iPadOS versions, ranging from older versions to the newest available version. The issue does not appear to be isolated to a particular iPad model or iPadOS version.

We have also tested different file locations and network conditions. The problem occurs when:

  • Saving files locally on the iPad.
  • Saving to OneDrive.
  • Saving to iCloud.
  • Connected to Wi-Fi.
  • Connected through cellular service.
  • Using the device offline/in Airplane Mode.

We have tried troubleshooting the devices and Excel app extensively, but so far nothing has resolved the problem. Because Excel has become unreliable for our field operations, we have temporarily had to move our technicians to Google Sheets.

Given that the issue appeared almost simultaneously across 22+ devices with different hardware, iPadOS versions, storage configurations, network connections, and save locations, we are wondering whether there was a recent Excel for iOS/iPadOS app update or service-side change that could be responsible.

Has anyone else recently started experiencing similar issues with Excel for iPad — particularly freezing, extremely slow saving, failure to save, or the keyboard not appearing?

If Microsoft is aware of a current issue with Excel for iPad, is there a known workaround or an estimated fix?

    Yes. Similar reports exist for Excel on iPhone and iPad after recent app updates, including freezing on launch or during use. One accepted answer also states that a recent Excel update introduced a known bug and that it is not tied to a specific iOS version. That matches the pattern described across mixed iPad models, storage sizes, network types, and OS versions.

    Supported workarounds from the available guidance:

    1. Update Excel and the other Microsoft 365 apps from the App Store.
    2. After updating, sign out and sign back in, then restart the app and the iPad and retest.
    3. If Excel freezes, close it from the recent apps screen, restart the iPad, and relaunch Excel.
    4. On iPad, try resetting the app:
      • Open Settings
      • Select Excel
      • Under RESET, tap Reset Excel
      • Turn on Delete Login Credentials
      • Close Excel completely, then reopen it
    5. If needed, also try Settings > Excel > Reset > Reset Cloud Settings, then restart Excel.
    6. A reported temporary workaround for some iOS cases is to turn off Wi‑Fi or enable Airplane mode when the app freezes, regain access, then reconnect.
    7. If the issue continues, uninstall and reinstall Excel. Before doing that, make sure files are stored in OneDrive or another cloud location so work is not lost.

    For Microsoft-tracked iOS app sign-out instability, the documented next step is to install the latest app updates because fixes are being rolled out through the App Store. If the problem still reproduces after updating and resetting, collect diagnostics by submitting Send a Frown feedback after reproducing the issue and record the Session ID, app version, device details, and screenshots.

    No estimated fix date is provided in the available material.

    Dear Kane Wyatt,

    Thank you for providing the detailed information regarding the Excel for iPad issue.

    As an initial troubleshooting step, please follow the recommendations provided by AI Assist, including updating the Excel app and iPadOS to the latest available version, and resetting the iPad, then check whether the issue persists.

    If the issue continues, since the same symptoms are occurring across approximately 22 devices with different iPad models, iPadOS versions, network connections, and storage locations, I sincerely recommend you try to create a support ticket from: Microsoft 365 Admin Center>Support>Help & Support. You can raise support ticket from: https://admin.microsoft.com/Adminportal/Home?#/support/requests

    The support team over there has higher permission than us to investigate the issue from background, they have more resource and correct escalation channel in handling this kind of issues. This would be a more efficient way in handling the case for you.  

    For reference:  Get support | Microsoft Docs       

    Thanks for your patience and understanding so far.  Hope you having a nice day and really much warm regards to you as well!
