A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Hi Govindarajan,
Thanks for using Microsoft products and posting in the community, I'm glad to offer help.
According to your description, I tested on my side, when selecting a Pivot Chart, whether it is the copy option in the context menu, in the Home tab, or the shortcut keys Ctrl + C are all working, and I can paste the copied Pivot Chart to another sheet or workbook properly.
In your case, please try to create a new workbook and check if the problem persists, if it affects the newly created workbook, there may be something wrong with the installation, you can try to perform an online repair to see if it can help you fix it: Repair an Office application
Besides, please go to File > Account to take a screenshot of the Product Information, it would be helpful for us to check if it caused by certain version, as shown below, please note to mask your email address.
Please feel free to let me know if there is any progress, I'll continue to help you.
Best Regards,
Arck
