Import of goods from the store on Opencart platform Shafa.ua

Need to find a solution for bulk upload of products on the Closet. All goods uploaded to the site on the Opencart platform. Unloading can be done directly with opencart or xml file.
Waiting for your suggestions for solving this problem and cost.

On Shafa.ua you can download the product only in manual mode. This is the main problem. That is, the functionality for loading price lists no no.
