Run Excel in Safe Mode to Disable Add-ins

Starting Excel in Safe Mode helps determine if a third-party add-in is causing the dialog box to truncate.

Sometimes, incompatible add-ins can interfere with older legacy dialog boxes in Excel. Safe Mode bypasses all add-ins and custom toolbar settings.

1
Open the Run Dialog

Press the Windows key + R on your keyboard to open the Run dialog box.

2
Launch Safe Mode

Type 'excel /safe' in the Run box and press Enter or click OK.

3
Test Microsoft Query

Open your workbook and launch Microsoft Query to see if the window displays correctly. If the window is no longer cut off, an add-in is the culprit and should be disabled from File > Options > Add-ins.

Identifying Problematic Add-ins: If Safe Mode resolves the issue, disable all add-ins first, then re-enable them one by one to find the specific add-in causing the truncation.

Frequently Asked Questions

Why does the Microsoft Query window get cut off in Excel?

This issue is most commonly caused by incompatible third-party add-ins, incorrect Windows display scaling settings (especially on high-resolution monitors), or corrupted Office installation files.

How do I check my exact Excel version for troubleshooting?

Open Excel, click on 'File' in the top-left corner, and select 'Account' from the bottom left menu. Your version, build number, and update channel will be clearly displayed under the 'About Excel' section.

Will an Office Quick Repair fix UI truncation issues?

A Quick Repair might resolve minor configuration issues without needing an internet connection. However, for stubborn UI bugs like a cut-off dialog box, an Online Repair is highly recommended as it completely verifies and reinstalls the application files.

Can a dual-monitor setup cause Excel dialog boxes to render incorrectly?

Yes, dragging an older Excel dialog box between monitors with drastically different scaling percentages (e.g., 100% on one and 150% on the other) can sometimes cause the window to truncate. Setting both monitors to the same scaling can serve as a temporary workaround.
