Hello Peoples

I already installed a shopping cart using zen-cart and successfully installed the easy populate module also. My buyer having lots of data to import in that site. All the data are having different sizes and colors. For the size & color options we already using the attributes modules to mention.

Now the problem is we need to import all the size and colors of the products by the import file via zen-cart. But easy-populate not supporting to import us. It have any possible way to import size and colors via easy populate? If no the please advise me a alternate method to import. Thanks .
