With Shopify, you are able to import existing customers information by using customer CSV file. In computing, CSV stands for Comma-separated Values. The CSV file is a delimited text file that allows data to be saved in a table-structured format. Each line is a data record in which each value is separated by commas.

In order to import your database from other platforms like Google Sheet or Microsoft Excel to Shopify admin account, you need to export it to .csv format first. Currently, Shopify only supports UTF-8 encoding. Therefore, in order to avoid some incorrect characters appeared in your data from transporting between platforms, we suggest you should remember to transform your data to the proper format (.csv with UTF-8 encoding) before importing to Shopify.
