BigCommerce exports have the same holes as Woo and Shopify.

Blank SKUs, $0 prices, products with no image, two rows sharing a SKU. You do not need a BigCommerce app. Export products and check the file in the browser.

Open the CSV check

How

1. BigCommerce admin → Products → Export.
2. Open csv-check.html and drop the file. Nothing is uploaded.
3. If column names look like a Shopify export, the checker uses Shopify rules. Otherwise it looks for SKU, name, price, and image columns.
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 BigCommerce App Marketplace app and does not connect to your store. WooCommerce merchants who want an on-site plugin can use Catalog Audit. Shopify notes: shopify.html.
