I have no idea if there are any plugin allowing this, but if you don't mind using a bit of SQL you can extract it this way:
SELECT u.ID, u.user_login, u.user_email, u.user_registered, u.display_name, b.path
FROM wp_users u
LEFT JOIN wp_usermeta um ON um.user_id = u.ID
LEFT JOIN wp_blogs b ON um.meta_key LIKE CONCAT_WS('_', 'wp', b.blog_id, 'capabilities')
WHERE um.meta_value LIKE '%"administrator"%' OR um.meta_value LIKE '%"editor"%';
This will produce the following resultset:
+----+------------+---------------------+---------------------+--------------+----------------+
| ID | user_login | user_email | user_registered | display_name | path |
+----+------------+---------------------+---------------------+--------------+----------------+
| 1 | jdoe | [email protected] | 2014-12-02 10:46:26 | John Doe | /subsite-path/ |
+----+------------+---------------------+---------------------+--------------+----------------+
where ID, user_login, user_email, user_registered and display_name are user's details while path is the subsites URL (you might want to select domain instead of path if your network install is domain based and not directory based)
Note that this will produce one row per site where the user is registered, which means that if you have a user registered as an admin on one site and as an editor on the other, the query will produce 2 rows for this user.
Using GROUP_CONCAT you can concatenate all these rows into one:
SELECT u.ID, u.user_login, u.user_email, u.user_registered, u.display_name, GROUP_CONCAT(b.path ORDER BY b.path SEPARATOR '\n')
FROM wp_users u
LEFT JOIN wp_usermeta um ON um.user_id = u.ID
LEFT JOIN wp_blogs b ON um.meta_key LIKE CONCAT_WS('_', 'wp', b.blog_id, 'capabilities')
WHERE um.meta_value LIKE '%"administrator"%' OR um.meta_value LIKE '%"editor"%'
GROUP BY u.ID;
This will produce the following resultset:
+----+------------+---------------------+---------------------+--------------+-----------------+
| ID | user_login | user_email | user_registered | display_name | path |
+----+------------+---------------------+---------------------+--------------+-----------------+
| 1 | jdoe | [email protected] | 2014-12-02 10:46:26 | John Doe | /subsite1-path/ |
| | | | | | /subsite2-path/ |
+----+------------+---------------------+---------------------+--------------+-----------------+
