Which e-commerce platforms can I import products to?

Product Upload publishes to five platforms, each with its own connection method.

Platform	How it connects
Shopify	Native app in your store admin
Wix	Native app in your store admin
WooCommerce	Free WordPress plugin, or CSV export
BigCommerce	CSV export only (no store connection)
Squarespace	API key you generate in Squarespace

BigCommerce is the one platform with no store connection: Product Upload builds a BigCommerce-formatted CSV that you upload yourself. The others create the products in your store for you. Squarespace connects with an API key you generate under Settings > Developer Tools, and publishes one variant per product, so use the CSV export instead when a product has options.

Grab free, correctly formatted CSV templates for every platform at productupload.co/resources/templates.
