To import customers into WooCommerce, you should use a high-quality third-party plugin. The alternative is to custom code a solution, which isn't particularly wise, since you'd have to write data to core WordPress tables such as wp_users and wp_usermeta.<\/p>\n\n\n\n
If you also want to import WooCommerce order data and link that data to your imported customers, you'd have to overwrite the _customer_user field of the wp_postmeta table so that it uses the new user IDs generated by your WooCommerce customer import.<\/p>\n\n\n\n
Put another way, importing customers into WooCommerce using custom code is not for the faint of heart. You're much better off leaving this to a true-and-tried professional plugin.<\/p>\n\n\n\n
The best plugin on the market to perform this task is WP All Import. Not only will it allow you to import customers into WooCommerce. It will also handle any linking issues between WooCommerce customers, orders, and products. If any other themes or plugins have added additional customer fields, it will let you import data into those fields, too. And if you need to filter your customer imports or schedule them to occur on a regular basis, it does that, as well.<\/p>\n\n\n\n
As we recommend with most data imports that affect core WordPress or WooCommerce tables, we strongly advise you to back up your website's database before attempting your customer import. To be absolutely sure that you have a viable recovery process, you should restore this data to a test site, then check to make certain the data looks okay before proceeding.<\/p>\n\n\n\n
It's unlikely that you'll ever need a backup when using a proven plugin like WP All Import, but as the saying goes, it's always better to be safe than sorry.<\/p>\n\n\n\n
