Variant Check

Variant Check is a downloadable offline CSV checker from Paperstack, a Meltemi Labs project. It reviews files prepared for WooCommerce’s built-in product importer: duplicate SKUs, repeated parent/attribute combinations, unresolved parent references, parent types and row order, basic price formats and local attribute relationships. An optional existing-store export helps resolve parent SKUs and product IDs. Findings include source line numbers and can be exported as CSV. The price is US$9 once, including the HTML tool, JavaScript source, 31 tests, fictional sample, a single-user licence permitting paid client work and seven days of defect support. Email delivery is within one business day; there is a 30-day money-back guarantee. Catalogues stay on the user’s device; no AI calls, accounts or WordPress installation. Code and documentation developed with AI assistance. It does not import or rewrite files. Store state, global taxonomy slugs, custom schemas, plugins, images and import success are not verified. Review every finding and test on staging. A public fictional-sample demo is on the product page. Independent product, not affiliated with WooCommerce.
