Microsoft Excel was unresponsive since 7/7/2026
Good morning,
Microsoft Excel has been unresponsive since 7/7/2026. When alternating between 2 excel sheets to copy data, the Excel sheet will become unresponsive and I have to restart my computer multiple times.

Hi Ei Li,
For this issue, we’ll investigate it further when it occurs again so we can identify the root cause.
Based on the symptoms, the issue may be caused by the workbook containing a large amount of data, complex formulas, or other factors affecting Excel’s performance. We will perform further checks once the issue can be reproduced.
In the meantime, we recommend keeping a backup copy of the file on your local PC or Google Drive. This will ensure you have a copy available in case the file becomes corrupted or cannot be opened.
Please let us know if the issue happens again and, if possible, avoid restarting your computer immediately so we can check the Excel file and system behavior first.
