For users with people permissions: navigate to the People page. Under the Everyone heading, select Export All People.

A green banner will appear at the top of the interface confirming your selection. The banner reads as follows: "Your people export CSV is being prepared. We'll email you a link to download it in a few minutes."

Note: The all people report contains both active and archived users. Archived users are denoted by a TRUE value in the Archived column.

To download a report of only a certain group's members, navigate to the group's overview page by selecting its name from the left-hand menu of the People page, then select Export Group Members.

Like the all people report, the group members report contains both active and archived users.
