The exported Excel file supports the same hierarchy than the add-on, so rows can be collapsed and expanded:

In Jira Cloud there is only one option to export to Excel. The Export to Excel will download an Excel file with the currently displayed issues (nodes) in the hierarchy. If an issue has its children hidden (the issue is collapsed), then the no visible children will not be exported even they are loaded in the hierarchy, but not visible.

The exported fields for an issue are the same as those shown in the Hierarchy layout for the issue. If a field, for example 'labels', has no value for any issue in the hierarchy, it will not be exported to excel.
