Hi @Thomas Reed,
Welcome to Microsoft Q&A forum.
Thank you for reaching out and providing those details. We sincerely apologize for the inconvenience this issue has caused.
The issue you described relates to checkboxes in your Excel workbook not appearing in the desktop application, even though they are visible when opening the file in a browser. This behavior typically occurs due to recent updates in Excel or rendering settings on the local machine.
Recent updates to Excel have modified how checkbox controls are displayed. As a result, older checkbox elements may not render correctly in certain desktop builds, even though their linked cell values (TRUE/FALSE) continue to function as expected. In contrast, Excel Online uses a different rendering engine, which ensures that checkboxes appear correctly in the web version.
To better understand your environment and provide the most accurate solution, could you confirm:
- Which version and build of Excel are you currently using? (You can check under File > Account > About Excel.)
- Are the checkboxes created using Form Controls, ActiveX Controls, or the new in-cell checkbox feature?
- Have you recently installed any Office updates or add-ins?
- Does the same file show checkboxes correctly on another computer with Excel desktop?
- Which OS version are you running (Windows 10, Windows 11, macOS)?
- Is hardware graphics acceleration enabled in Excel? (Check under File > Options > Advanced > Display.)
While we wait for your response, here are some steps you can try for your situation:
1/ Begin by updating Excel to the latest version to ensure compatibility with recent rendering changes.
- Go to File > Account > Update Options > Update Now to ensure you have the latest build.
2/ Next, enable the Developer tab in Excel to access advanced controls and customization options.
- Navigate to File > Options > Customize Ribbon, then check Developer.
- From Developer > Insert, you can re-add checkboxes if needed.
- Or you can choose All Commands > scroll down to Checkbox > Add to New Group

3/ Then, perform an Office repair to restore default functionality and ensure all components are working correctly.
- Open Control Panel > Programs > Microsoft Office > Change, then select Quick Repair or Online Repair.
4/ After repairing Office, test Excel in Safe Mode to determine if add-ins or custom settings are causing the issue.
- Press Win + R, type
excel /safe, and check if the checkboxes appear. If they do, an add-in may be causing the issue.
5/ For a more efficient resolution, we recommend using your administrator account or contacting your IT administrator to submit a support request directly to Microsoft Support team.
They can raise a support ticket by visiting: Get support - Microsoft 365 admin | Microsoft Learn
