The newest version of Copy From Excel requires an additional step (clicking Ctrl + V) to complete the pasting process.
If you used Ctrl + V and the data isn't pasting, the issue might be related to your internet settings. First, try clearing all of your cookies and temporary internet files. If that doesn't work, you can try completing the function in a different web browser.
If you are still having issues after trying the steps above, please contact Fundriver Support for assistance.
