Fix Slow Copy and Paste Clipboard Errors in Microsoft Excel
Question details
Users experience severe delays and recurring error messages stating 'There is a problem with the clipboard' when attempting to copy and paste data in Excel, even within a completely blank workbook.

- Product
- Microsoft Excel
- Device & OS
- Windows
- Scenario
- Copying and pasting data across cells or between workbooks in Excel.
- Observed behavior
- Excel becomes extremely unresponsive during copy-paste operations and repeatedly displays a 'There is a problem with the clipboard' warning message.
Save your current work and close any background clipboard managers, remote desktop tools, or screenshot utilities, as these third-party background applications frequently lock the Windows clipboard and conflict with Excel.
Launch Excel in Safe Mode and Manage Add-ins
Running Excel in Safe Mode bypasses all add-ins. If the clipboard works perfectly here, a third-party add-in is likely causing the slow performance.
Many performance issues in Office applications are triggered by outdated or incompatible COM add-ins that monitor clipboard activity.
Press the Windows key + R on your keyboard to open the Windows Run dialog box.
Type 'excel /safe' into the text box and press Enter to launch Microsoft Excel in Safe Mode.
Try copying and pasting data. If the error is gone, navigate to File > Options > Add-ins.
Select 'COM Add-ins' from the Manage drop-down menu at the bottom and click 'Go'. Uncheck all add-ins, click OK, and restart Excel normally to isolate the problematic add-in.

Perform a Windows Clean Boot to Stop Background Conflicts
Background applications and third-party utilities can interfere with Microsoft Office. A clean boot ensures only essential system services are running.
Run the Microsoft 365 Repair Tool
If Excel's core files are corrupted, running the built-in Office repair tool can restore normal clipboard functionality.

Frequently Asked Questions
Why does Excel say 'There is a problem with the clipboard'?
This error usually occurs when another application, such as a third-party clipboard manager, remote desktop tool, or web browser, is actively locking the Windows clipboard while Excel is trying to access it.
How do I clear the clipboard in Microsoft Excel?
To clear the Office Clipboard, go to the Home tab on the ribbon, click the small launcher arrow in the bottom-right corner of the Clipboard group to open the Clipboard task pane, and click the 'Clear All' button.
Will reinstalling Office fix slow copy and paste issues?
Reinstalling or running an Online Repair can fix corrupted installation files that cause clipboard errors. However, if the issue is triggered by a third-party add-in or a background app, you must identify and disable that specific app first.
Does Live Preview affect copy and paste speed in Excel?
Yes, the 'Enable Live Preview' feature can sometimes slow down pasting operations. You can disable it by navigating to File > Options > General, and unchecking 'Enable Live Preview' under the User Interface options.
