Was able to successfully import customer list in magento 2 backend via Data Transfer-Import, however the list didn’t show up in customers section when the system reindexed.
header for the list includes the following: email, _website, confirmation,created_at, created_in, disable_auto_group_change, dob, firstname, gender, group, lastname, middlename, password_hash, prefix, rp_token, rp_token_created_at, suffix, taxvat, updated_at, website_id, password.
Some are of course left blank but others are filled in. Was able to import the new files with these headers but so far, none of the customers and their emails are showing.
