Device & OS
not provided
Scenario
A user works with Excel worksheets and imports TXT reports from an ERP system.
Observed behavior
Excel hangs or closes during these operations. Outlook has also restarted while searching old messages.
Before you start

Note whether the crash occurs in every workbook or only specific files, and record how you import the TXT reports. The steps below use Windows controls; if your organization manages updates or settings, contact your IT administrator when access is restricted.

Solution 1Recommended

Update Office and Windows, then test Excel in safe mode

Use updates and safe mode to check whether an outdated installation or an add-in is contributing to the crashes.

1
Update Office

In Excel, open File > Account > Update Options > Update Now. If updates are managed by your organization, ask your IT administrator to check them.

2
Update Windows

Open Windows Settings > Windows Update and select Check for updates. Install available updates and restart if prompted.

3
Start Excel in safe mode

Close Excel, press Windows+R, enter excel /safe, and select OK. Try saving a workbook, deleting a sheet, and importing a TXT file.

4
Check add-ins

If safe mode prevents the crash, open Excel normally and go to File > Options > Add-ins. Select COM Add-ins in the Manage list, click Go, and clear add-ins to test them; re-enable them one at a time to identify a possible cause.

Update Office and Windows, then test Excel in safe mode
Safe mode results: If Excel still crashes in safe mode, an add-in is less likely to be the sole cause. Continue with the clean boot and repair checks.

Frequently Asked Questions

How do I tell whether an Excel add-in is causing the crash?

Press Windows+R, run excel /safe, and repeat the failing operation. If Excel works in safe mode, check File > Options > Add-ins and disable COM add-ins to test them.

Where can I find my Microsoft 365 version and update channel?

In Excel, open File > Account and look under Product Information. Record the version and update channel for your IT administrator or Microsoft Support.

What if Excel crashes only when I import an ERP TXT report?

Try importing the report into a blank workbook and note the import method, file format, and whether other TXT files also fail. Share those details with your IT administrator or Microsoft Support.

Does WPS Office repair Microsoft Excel crashes?

No. WPS Office is an alternative for working with compatible spreadsheet files; use Microsoft 365 Online Repair or Microsoft Support to troubleshoot Excel itself.
