Hello, Brian,
I can suggest checking the following demo showcasing how to paste data from excel to the Grid:

Also, if you need a more Excel-like experience, I can suggest checking our Spreadsheet component which is an Excel-like web component for data editing and management:
https://docs.telerik.com/kendo-ui/third-party/react#spreadsheet
Let me know if you need additional information on this matter.
Regards,
Stefan
