EShop CSV Advanced greek products import

Hello from Greece,
I am using csv advanced in the eshop .
I am importing products, categories etc. when the client page is set in english the things that i have imported are all visible. When i set the client language in greek all the products disappear. I realised that i must set the language in greek when i make the import file.
My question is how i am doing it. In your old csv advanced programm it had a field and you were choosing the language.
Pls answer me in detail because i am lost.
thanks in advanced.
Waiting for your reply.

Hello Loannis,

You should add the language field to the CSV file as well as in the template. In the CSV file, value of language field should be el-GR

By the way, if you have already had the data in English, then simply go to EShop -> System -> Tools -> Synchronize Data, then the system will copy the data from English to Greek for you automatically.

Sincerely, Giang
