Prepare two CSV files. The first file (File 1) should contain all the customer fields you want to set other than Address fields. The second file (File 2) should contain all the addresses you want to import with 1 address per line. 2. Link the two files together using a common field. This could be the External ID or any other unique identifier that is common to both files. 3. In NetSuite, navigate to Setup > Import/Export > Import CSV Records. 4. Select the record type as 'Customer'. 5. Choose 'Multi-File' as the import type. 6. Upload File 1 and File 2. 7. During the import process, NetSuite will ask you what field you want to use to link the files together. Choose the field you used to link the two files in step 2. 8. Map the fields in your CSV files to the corresponding fields in NetSuite. 9. Review your mappings and start the import. 10. Once the import is complete, the new addresses will be added to the existing customers. Remember, each address must have a unique label. Also, if the 'header' (other customer) data isn't clean, you might end up accidentally creating other customers and duplicate addresses. It's always a good idea to double-check your data before starting the import.
