Solution 1Recommended

Launch Excel in Safe Mode and Disable Faulty Add-ins

Running Excel in Safe Mode bypasses add-ins and custom settings, helping to identify if a third-party extension is causing the freezing issue.

Add-ins designed to enhance Excel can sometimes conflict with clipboard operations, leading to unresponsive behavior during copying or pasting.

1
Open the Run dialog

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

2
Launch in Safe Mode

Type 'excel /safe' (without quotes) and press Enter to launch Excel in Safe Mode.

3
Test the workbook

Open your workbook and attempt to copy and paste data. If it works smoothly, the issue is likely caused by an add-in.

4
Disable add-ins

Go to File > Options > Add-ins. Select 'COM Add-ins' from the Manage drop-down menu at the bottom and click Go. Uncheck all active add-ins, click OK, and restart Excel normally.

Launch Excel in Safe Mode and Disable Faulty Add-ins
Identify the Culprit: If disabling all add-ins fixes the issue, turn them back on one by one and restart Excel each time to identify which specific add-in is causing the freeze.

Frequently Asked Questions

Why does Excel hang only when pasting data from web browsers or other applications?

This happens because Excel attempts to process complex HTML formatting or embedded objects from the external source. To prevent this, use 'Paste Special' and select 'Text' or 'Values' to paste only the raw data without the heavy formatting.

Can a corrupted workbook cause freezing during formatting?

Yes. Severe corruption in the file's underlying XML structure can crash Excel when modifying formats. Try using the 'Open and Repair' feature found in the Excel Open dialog to fix the workbook.

Does the Windows clipboard history affect Excel copy-paste performance?

A bloated clipboard history can slow down clipboard operations across your system. Press Windows + V to open the clipboard history and click 'Clear all', or clear the Office Clipboard from the Home tab to restore performance.

How can I safely share a freezing workbook with support for troubleshooting?

Make a copy of your workbook, replace all sensitive data with dummy text, and delete any confidential sheets. You can then share this sanitized file via a secure private message or a private OneDrive link with the support team.
