# Customers import via CSV file

[](#)  [ Customers Handling API ](https://documentation.netstorming.net/customers-handling-api)      Customers import via CSV file    

We can import a customers list via a CSV file.
This is a one-time operation and should be run only at system setup time.
If you want to bulk-insert customers with your ststem already installed, you should use our [Customers Handling API](https://documentation.netstorming.net/customers-handling-api/basic-rules).

In order to import your data, you must produce a CSV that **exactly matches** the format documented in [client\_import\_fields\_list\_with\_users.xlsx](https://documentation.netstorming.net/customers-handling-api/customer-import-via-csv-file/client_import_fields_list_with_users.xlsx)

We will not be able to import incomplete or incorrect files.
