Hello @RabbitKoshana
You can import your customers in Shopify.
If you want to create the user account for those customers then Shopify API also provides the API to create customers account.
Hope this information will help you.
If you are on shopify plus you could use multipass https://shopify.dev/docs/admin-api/rest/reference/plus/multipass
