How to import the new users

When I export the users by using “Import users from CSV”.

There is a “submitted” column, the data looks like this:
a:23:{s:6:”gender”;a:1:{i:0;s:4:”Male”;}s:33:”having_rural_or_remote_background”;s:6:”Unsure”;s:33:”aboriginal_torres_strait_islander”;s:2:”No”;s:9:”subscribe”;a:1:{i:0;s:39:”Rural Health Workforce Australia (RHWA)”;}s:13:”area_of_study”;s:24:”Aboriginal Health Worker”;s:10:”university”;s:29:”Central Queensland University”;s:14:”privacy_policy”;a:1:{i:0;s:37:”Do you accept NRHSN’s privacy policy?”;}s:7:”form_id”;s:2:”31″;s:9:”timestamp”;s:10:”1578529914″;s:7:”request”;s:0:””;s:8:”_wpnonce”;s:10:”5955eeb72f”;s:16:”_wp_http_referer”;s:20:”/wordpress/register/”;s:10:”user_login”;s:6:”dlsm90″;s:10:”first_name”;s:6:”dlsm90″;s:9:”last_name”;s:3:”lee”;s:10:”user_email”;s:18:”[email protected]”;s:10:”birth_date”;s:10:”2020/01/08″;s:13:”mobile_number”;s:10:”0285421652″;s:17:”student_id_number”;s:8:”s5216565″;s:27:”year_of_expected_graduation”;s:4:”2022″;s:9:”job_title”;s:5:”trest”;s:10:”start_date”;s:10:”2020/01/08″;s:8:”end_date”;s:10:”2020/01/30″;}

If I ignore this field, the Info button won’t be showing in the backend. Is there an easier way to import?
