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.

How to Fix Slow Copy and Paste and Clipboard Errors in Excel
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.
Before you start

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.

Solution 1Recommended

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Many performance issues in Office applications are triggered by outdated or incompatible COM add-ins that monitor clipboard activity.

1
Open Run Dialog

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

2
Start in Safe Mode

Type 'excel /safe' into the text box and press Enter to launch Microsoft Excel in Safe Mode.

3
Test Copy and Paste

Try copying and pasting data. If the error is gone, navigate to File > Options > Add-ins.

4
Disable COM 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.

Launch Excel in Safe Mode and Manage Add-ins
Safe Mode Verified: If Safe Mode resolves the issue, you can permanently fix it by leaving the conflicting add-in disabled.

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.
