How to Fix the Numbers About the App Popup in Shared Excel Workbooks
Product
Microsoft Excel
Device & OS
not provided
Scenario
Scrolling or pulling down from the top of the page within a shared Excel workbook.
Observed behavior
A popup displaying 'NUMBERS ABOUT THE APP' appears on screen. This issue is isolated to a specific shared file and does not occur in newly created workbooks.
Before you start

Before troubleshooting, save a local backup copy of the shared workbook to ensure no collaborative data is lost while testing.

Solution 1Recommended

Test the Workbook in Safe Mode

Opening Excel in Safe Mode temporarily disables third-party add-ins, helping you determine if an extension on a collaborator's machine is causing the popup.

Since the issue is isolated to one shared workbook, the popup is likely triggered by a specific add-in or custom setting introduced by another user's environment. Safe Mode is the best diagnostic tool for this.

1
Close Microsoft Excel

Ensure the affected shared workbook and the Excel application are completely closed.

2
Open the Run dialog box

Press the Windows Key + R simultaneously on your keyboard.

3
Launch Excel in Safe Mode

Type 'excel /safe' into the text box and press Enter or click OK.

4
Open the shared workbook

Go to File > Open within Safe Mode, browse to the affected shared workbook, and pull down from the top of the worksheet to see if the popup still appears.

Test the Workbook in Safe Mode
Identify the Culprit Add-in: If the popup does not appear in Safe Mode, navigate to File > Options > Add-ins in standard mode to disable third-party add-ins one by one until you find the source of the issue.

Frequently Asked Questions

Why does the 'Numbers About the App' popup only happen in one shared file?

This indicates the problem is isolated to the specific file's settings, custom macros, or a third-party add-in that was introduced by another user's computer, rather than a system-wide error in your Excel application.

How can I find out which collaborator caused the popup issue?

You can check the 'Version History' in OneDrive, SharePoint, or your native cloud storage to see which user last modified the document right before the popup started appearing.

Will copying the data into a new workbook stop the popup?

Yes, copying only the raw data (values and formatting) into a brand-new, unshared workbook often strips out the hidden background settings or corrupted elements triggering the popup.
