Hi @at_mahajan23 ,
Have you tried ACS User Exporter?
Navigate to http://localhost:4502/miscadmin#/etc/acs-commons/exporters and create a new Users to CSV Export page.
Name the page appropriately as the page’s report configuration can be saved and run again later.
Optionally, click Save Configuration at the top to save this configuration to this page. Multiple User to CSV Exporter pages with different configurations can be created.
