WSH Bulk Taxonomy Editor for WooCommerce updates product categories for the products you select in WooCommerce > Products.
Choose products, pick categories, preview the result, then apply the change in batches. The preview uses the same Add and Replace rules as Apply. Nothing is saved during preview.
This plugin edits product categories (product_cat) on the product itself. It does not edit product tags, attributes, or brands.
There is no product-count limit and no license check in this plugin.
Categories belong to the product, not to a variation. If a variation ID is submitted, the change is saved on its parent product. The same parent is only written once in a batch.
