Import Customer along with its Address and Contact

I want to import bulk Customer Data but how can i create thier address and contact at same time.
So that the address and contact link with that customer. If I do manually then there are more time consumable and there could be error.
Is There any way to import address ,contact and customer data so import at a time and it link with each other. By Script Or Customisation

Hello @Mack , Yes it’s possible to import address, contact, and customer data with script; for that, we need to write a custom script based on the data we have in an Excel or CSV file.
