- Product
- Microsoft Excel
- Device & OS
- not provided
- Scenario
- Renaming an Excel worksheet tab after recently installing a Microsoft 365 update.
- Observed behavior
- Characters typed while renaming the sheet are delayed on screen, causing text input to be missed or duplicated.
Before troubleshooting, check if the typing delay occurs in a brand-new, blank Excel file or only in specific documents with complex formatting.
Run Excel in Safe Mode and Disable Conflicting Add-ins
Identify if a third-party COM or Excel add-in is causing the interface lag during sheet renaming.
Add-ins can sometimes conflict with recent Office updates, causing performance issues in the Excel interface.
Press Windows + R, type 'excel /safe' in the Run dialog, and press Enter to open Excel in Safe Mode. Check if the renaming delay persists.
If the issue is resolved in Safe Mode, restart Excel normally. Navigate to File > Options > Add-ins.
At the bottom of the window, select 'COM Add-ins' from the Manage dropdown and click Go. Uncheck all listed add-ins and click OK.
Double-click a sheet tab to rename it. If the delay is gone, re-enable your add-ins one by one to identify the specific culprit causing the conflict.

Roll Back to a Previous Version of Microsoft Office
If the issue started immediately after a specific Office build update, reverting to an earlier version can bypass the bug until Microsoft patches it.
Apply the Temporary Zoom Workaround
A quick visual refresh by changing the zoom level can temporarily resolve the interface lag when renaming tabs.

Frequently Asked Questions
Why is my Excel lagging when I type?
Typing lag in Excel is frequently caused by conflicting add-ins, graphics hardware acceleration issues, or bugs introduced in recent Microsoft 365 updates. Starting Excel in Safe Mode can help determine if a third-party add-in is the root cause.
How do I report a bug or performance issue to Microsoft?
You can report issues directly from Excel by navigating to File > Feedback > Send a Frown. Be sure to include your exact build number and a detailed description of the typing delay experienced when renaming sheets.
Can changing the zoom level really fix Excel interface lag?
Yes, in some cases, toggling the zoom level (for instance, from 100% to 90% and back) forces Excel to refresh its visual rendering of the interface, which can temporarily bypass minor display and input lags during your active session.
Will rolling back an Office update delete my Excel files?
No, reverting to an earlier version of Microsoft Office only affects the application software. Your saved workbooks, spreadsheets, and personal files will remain completely unaffected and safe.
