PrestaShop exports have the same holes. You do not need a module.

Blank product references, $0 prices, products with no image, two rows sharing a SKU. Export products and check the file in the browser.

Open the CSV check

How

1. PrestaShop admin → Catalog → Products → Export, or Advanced Parameters → Import/Export.
2. Open csv-check.html and drop the file. Nothing is uploaded.
3. The checker treats Reference as the SKU, plus Name, Price, and Image URL.
4. Fix the SKUs that cannot sell. A ranked Monday list of 20 is the Store Audit (USD $149) — email the same CSV to info@shopgaps.com.

ShopGaps is not a PrestaShop Addons module and does not connect to your shop. WooCommerce merchants who want an on-site plugin can use Catalog Audit. Magento notes: magento.html.
