I can not find any way to export the reports in the Report center, EPiServer CMS.
It's not implemented?
No, exporting reports to Excel is not implemented out of the box. Report Center has stayed unchanged for a number of years.
There is a code solution for it in this blog: https://world.episerver.com/blogs/Henrik-Fransas/Dates/2016/3/create-custom-report-in-mvc-with-excel-export/
I've been thinking about the report center lateley and it must be the feature I've used the least in all my years in Episerver development. I really think it has potential to be a very useful feature for editors / site admins.
Excel export out of the box would be nice and why not the possibility to setup and schedule the report so I for instance would get an overview om broken links in my mailbox every week.
I agree Per! Transforming the Report Center into a query builder with export possibility would greatly increase its potential.
