WooCommerce Guidelines to Avoid Product Duplication

Seeing shop owners struggling to upload products, WooCommerce decided to create a solution that will help them. First, they released an extension “Product CSV Import Suite”.

This extension lets vendors import thousands of products and supports complex products and custom data from Bookings, Product Vendors, Brands, Google Product Feed and more.

However, when WooCommerce 3.1 was released they added a product export/import tool in the core plugin. So, shop owners can upload all product information to WooCommerce, including name, short description, regular price & sale, and more. 

They can also import any standard product type, with variations using a single CSV file. Now, when uploading a CSV file, they added some guidelines. Like,

  • CSVs should be in UTF-8 format
  • You should define Dates for the store’s local timezone.
  • Use 1 or 0 in your CSV
  • Multiple values in a field get separated with commas
  • Wrapping values in quotes allows you to insert a comma
  • Prefix the id with id: if referencing an existing product ID. No prefix is needed if referencing an SKU. For example: id:100SKU101
  • Custom meta is supported/imported but only plain text – no support for JSON or Serialized data
  • Taxonomy term hierarchy is denoted with >, terms are separated with commas
  • Draft products are not exported, only published and privately published products.

So, if you follow these guidelines, you must be able to avoid the issue of product duplication while importing products on WooCommerce.
