Hi,
There is no way to do that.
First, you would have to open the xlsx with libreoffice calc or office excel and modify the columns to match HikaShop's columns, and save it as a CSV, and then upload via FTP the images in the images/com_hikashop/upload/folder an then you could import the CSV in HikaShop.
If it's only one big xlsx file with all the products data in it, that should be no problem doing it like that.
But if you have one zip file for each product, then that would either require:
- I think that RO CSVi can import XML files directly, and I think they have a "template" mechanism where you can save the columns conversion so that you don't have to do it each time:

It would need some confirmation from them, but I think that would allow you to rapidely import the products data once setup.
- A script developed specifically. The script could even get directly the ZIP file, extract it, move the image files where they should go and run the import all automatically. That would require a developer to work on it so it would of course be the most expensive solution but the easiest for you.
