Hi,
EO.Web Grid does not provide any direct support for that. What you can do is to:
1. Place a "Paste into Grid" button in your page;
2. When user clicks that button, display a dialog with a textbox prompting user to paste into the textbox;
3. Use JavaScript to parse the text user entered, then use the Grid's client side API to add data into the Grid.
You can find more information about how to use our client side API here:
