Hi Vern,
The Excel Links are a Catch-22. You could create two reports (with links and without links), but that seems inefficient.
When a Workfront report is exported to Excel, two tabs are included. The first has formatting, groupings, and active hyperlinks. The second is just raw data with no hyperlinks.
Perhaps training end users outside Workfront to delete the former would be the easiest way to keep them out of hyperlink trouble, while still allowing your Workfront Users to take advantage of the hyperlinks.
Regards,
Doug
