Way 1: Restart Your PC to Fix My Excel 365 Freezes When Copying and Pasting

A simple yet effective way to address Excel 365 freezing issues is by restarting your PC. Restarting can clear out any temporary glitches or bugs that might be causing Excel to freeze.

Here's how you can do it:

  • Make sure to save all your work in Excel to prevent any data loss.
  • Close Microsoft Excel to ensure it is not running in the background.
  • Access the Start Menu, locate the Power Options tab, and choose 'Restart'. This action will reboot your computer, flushing out any temporary bugs or glitches.

After your computer restarts, open Microsoft Excel again and check if the performance has improved. This easy step can often resolve many common issues, including the freezing problem in Excel 365.

Way 2: Clear All Conditional Formatting

Conditional formatting is great for highlighting data, but too much of it can bog down Excel, especially during copy-paste actions.

Here’s a simple guide to clear conditional formatting:

  • Open the Excel file where you’re experiencing issues. Ensure it’s the specific file where the freezing occurs.
  • Click on the ‘Home’ tab. Then navigate to ‘Conditional Formatting’ and select ‘Clear Rules’. This option is crucial for removing excessive formatting that might be slowing down the program.

  • Choose the right option from the rules list to clear the formatting. This step depends on whether you want to clear rules from the entire sheet or just a selected area.

After completing these steps, restart Excel to see if the problem has been resolved. This method can significantly improve Excel’s performance by eliminating unnecessary formatting that may be causing the freezes.

Way 3: Disable the Live Preview when Excel 365 Crashes

Another solution to fix Excel 365 freezes when copying and pasting is disabling the Live Preview feature. This feature, while useful for previewing changes in your document, can sometimes lead to performance issues.

Here’s how you can disable it:

  • Open Excel and go to ‘File’ > ‘Options’. This will take you to the main settings area of Excel.
  • In the ‘General’ section, look for the ‘User Interface options’. Here, you’ll find a checkbox for ‘Enable Live Preview’. Uncheck this box to disable the feature.

    disable the live preview
  • Click ‘OK’ to save your changes. This action confirms that the Live Preview is now turned off.

After completing these steps, restart Excel and test if copying and pasting functions more smoothly. Disabling Live Preview can often result in a more stable Excel experience, especially when working with complex sheets.

Part 3: What Else Ways to Fix the Excel 365 Freezes When Copying and Pasting?

If you're still facing issues with Excel 365 freezing during copy and paste tasks, don't worry. There are more solutions to try out. Let's look at some other effective methods that can help solve this problem:

Way 1: Enable Safe Mode and Disable Add-Ins

One effective way to fix Excel 365 freezing during copy-paste operations is by disabling all add-ins. Add-ins are designed to enhance Excel's functionality, but sometimes they can conflict with the software, leading to performance issues.

Here's how to tackle this:

  • Use the keyboard shortcut Windows + R, type excel /safe in the input box, and hit Enter. This will open Excel in safe mode, a diagnostic mode where add-ins are disabled.
  • Once in Excel, click on ‘File’, then go to ‘Options’, and select ‘Add-ins’. This will show you all the add-ins currently in use.
  • At the bottom of the window, select ‘COM Add-ins’ and click ‘Go’. This brings up a list of all active COM Add-ins.

    enable safe mode
  • Disable these add-ins one by one. This process helps you identify which add-in might be causing the freezing issue. Once you find the problematic add-in, you can choose to remove it completely.

By following these steps, you can potentially resolve Excel’s freezing problem, ensuring smoother operation while copying and pasting data in your spreadsheets.

Way 2: Clear Cache Files to Fix Excel Freezes When Copying and Pasting

Sometimes, the issue of Excel 365 freezing when copying and pasting can be due to an overloaded cache. Clearing Excel's cache files might just be the solution you need.

Here's a easy way to do it:

  • Press Win+R on your keyboard to open the Run command dialog box.
  • In the dialog box, type %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\ and click 'OK'. This command navigates you directly to the folder where Excel’s cache files are stored.

    enable safe mode
  • In the opened folder, select all the files and delete them. This action clears all the cache files that might be causing the freezing issue.

This method is particularly useful if the freeze is cache-related, helping you get back to smooth and efficient operations in your spreadsheets.
