Many clients are utilizing Web Client On Premise.

There are many types of reports such as Management REporter, SSRS and Excel Reports

The SSRS reports and Management REporter reports work.

However, although users can see the Excel Reports in the List Pane, they cannot generate them from the Web viewer. Only the Desktop version of GP. Please add the ability to generate Excel Reports from the Web Client.

Thank you for your suggestion. We have reviewed this functionality ask previously.  Unfortunately, given the impact throughout the entire system and on customizations, this is not something we can consider at this time.. 
Best regards.
