Description

LineSW Feed Checker for WooCommerce helps store owners inspect supplier feeds before product data is written anywhere. It detects common CSV, XML and JSON formats, normalizes fields, compares feed rows with the current WooCommerce catalog, and exports dry-run reports for review.

The plugin is intentionally a checker and reporting tool. It writes plugin settings, presets, history and reports only. It does not create, update or delete WooCommerce products.

This WordPress.org package is a complete community checker for the features listed in this readme.

External services

This plugin connects only to supplier feed URLs entered by a site administrator.

When a preview or scheduled check runs, WordPress sends an HTTP GET request to the configured feed URL. The requested URL and normal WordPress HTTP request headers are sent to the supplier server that owns the feed. The feed response is used to build local diagnostics, history and exports.

The plugin does not automatically send feed data to LineSW or any other central API.

Product write policy

Automatic catalog writes, scheduled imports, media sideloading, price and stock updates, quarantine workflow, batch resume and approval tools are outside the scope of this WordPress.org checker package.

The WordPress.org plugin remains useful on its own: it checks real supplier feeds, shows mapping problems, detects risky rows, and exports reports that help decide whether an import workflow is ready.

FAQ

Does this plugin write WooCommerce products?: No. It checks supplier feeds, compares them with WooCommerce and exports dry-run reports. It does not create, update or delete products.
Why does the checker not write products?: Supplier imports can change prices, stock, categories, product status and images. This plugin focuses on the review step before those catalog writes happen.
Can I use it as a standalone checker?: Yes. You can use it to validate feeds, diagnose missing fields, compare supplier data with your catalog and export reports.
Which feed formats are supported?: The checker supports common CSV, XML and JSON feeds, including Heureka/Zbozi style SHOPITEM feeds, Google Merchant namespaced fields, Meta/Pinterest/TikTok style catalog fields, Shoptet-like CSV/XML exports, Shopify CSV, PrestaShop CSV, Adobe Commerce/Magento style exports and marketplace-style JSON payloads.
Can these standards be used for import too?: Yes. The checker treats them as import-ready profiles: it previews the feed, normalizes common fields and exports a dry-run import plan. Product writes are not part of this WordPress.org package.
Does this plugin export Google, Meta, Heureka or Zbozi feeds?: No. The WordPress.org checker recognizes, validates and documents those standards so a store owner can see whether product data is ready. Full outbound product feed generation is outside this checker package because it writes public feed files, schedules regeneration and needs channel-specific settings.
