Is it possible to download a file from workspace in HTML format instead of CSV or PDF?
gillesv68530862, it's not possible. Why do you need it?
I'd recommend creating an idea thread if you'd like to see this feature introduced.
When you send a report in HTML it could me more interactive. For example, when you have a dropdown list like this: Drop-Down Filters in Analysis Workspace - YouTube this is not supported in PDF.
