Thank you for your question. I am not sure I understand the question, are you asking about importing users via a CSV? If so, please look at our help documentation on how-to import users via a CSV (https://support.okta.com/help/Documentation/Knowledge_Article/People-1860061112). However, if you have a specific use case that is based on your environment, we recommend that you create a support case.
Thank you, Ruchir Parikh Technical Support Engineer.
