Is there a way to export Group Details? I've tried to look into the custom reports, and various report options, without success. Ultimately, it would be great if you could export group details similar to "actions" on other windows (i.e., Contact Search).
This is possible with SearchKit, but you'll need to be on the latest CiviCRM (5.42+) to export.
There isn't an export for this is CiviCRM, but you could select all the table entries on the screen and then paste it into Excel (or something similar), which would give you the information on this screen. Works if you have up to 100 groups and you set to 110 entries per page (or do it in multiple pages. And also expand any groups that are nested before exporting.
