How to Bulk Delete WooCommerce Products with Duplicate SKUs

Managing a growing WooCommerce catalog often leads to data inconsistencies, such as multiple products sharing the exact same SKU (Stock Keeping Unit). Whether caused by flawed CSV imports, accidental product duplication, or synchronization errors with external inventory systems, duplicate SKUs break inventory tracking systems, confuse fulfillment workflows, and create checkout errors.

How do I remove duplicate SKUs in WooCommerce?

Because WooCommerce does not have a native deduplication tool, the most reliable method is using the WooCommerce Products Spreadsheet plugin. By utilizing its Bulk Edit tool, you can scan your entire database, identify products sharing the exact same SKU, and automatically delete the duplicate entries while keeping the original product intact.

In this tutorial, we will walk you through the exact workflow to find and remove products with duplicate SKUs in bulk.

Critical Prerequisite: Prevent 404 Errors with 301 Redirects

When you delete products from WooCommerce, their front-end URLs are also removed, resulting in 404 “Page Not Found” errors. This negatively impacts user experience and SEO rankings. Before executing the mass removal of duplicate products, you must ensure traffic pointing to the deleted URLs is safely redirected to the remaining active product.

WP Sheet Editor provides an automated solution for this workflow. Follow these setup instructions before proceeding:

1. Install and activate the free Redirection plugin from the WordPress repository to handle the routing.
2. Install the WP Sheet Editor – Redirection extension to connect the spreadsheet actions to the routing plugin.

Once both tools are active on your website, you can run the Remove duplicates feature safely. Our plugin will automatically generate 301 redirects from the deleted duplicate products to the remaining primary product.

Best Practice: Always create a complete database backup before executing bulk deletion workflows.

Step-by-Step: Deleting Duplicate WooCommerce Products by SKU

First, navigate to WP Sheet Editor > Edit Products in your WordPress dashboard. This will load your entire catalog into the spreadsheet interface, displaying products as rows and data fields (like SKU, Price, and Stock) as columns.

Step 1: Open the Bulk Edit Tool

The Bulk Edit tool allows you to execute mass updates, including targeted data cleanup and deletion, across thousands of rows simultaneously.

Click the Bulk Edit button located on the top plugin toolbar.

Step 2: (Optional) Filter the Products You Want to Clean Up

If your goal is to scan the entire store for duplicate SKUs, you can bypass the filtering phase by selecting “Edit all the rows from my current search (including non-visible rows)” in the Bulk Edit dialog, and proceed directly to Step 3.

However, if you only want to remove duplicates within a specific category, brand, or product type, choose “I want to search rows to update and edit all the search results”.

This selection opens the Search tool, providing several parameters to narrow down the affected products:

• Contains keyword: Filter products containing a specific term in their title.
• Status: Target only published products, drafts, or private items.
• Enter Tags: Filter the list by category, product attribute, tag, or shipping class.
• Search on variations (Optional): Check this box if you need to identify and delete duplicate SKUs specifically found within product variations rather than simple products.

Once you configure your parameters, click Run search to apply the filters and return to the Bulk Edit configuration.

Step 3: Execute the “Remove Duplicates” Action on the SKU Field

With your target products loaded, configure the following exact values in the Bulk Edit tool to find and delete the duplicates:

• What field do you want to edit: Select SKU
• Select type of edit: Select Remove duplicates

Click Execute Now.

Verifying the Cleanup Process

The spreadsheet will process the command and automatically delete all redundant products that share an identical SKU, leaving only one unique product per SKU. By automating this workflow, you eliminate the need to manually audit your inventory list line by line.

Furthermore, because you installed the Redirection extension during the prerequisite phase, any URLs belonging to the deleted duplicates are now safely routing customers and search engines to the retained product, preserving your site structure and SEO health.
