Dear @spraveenitpro.
Thanks a lot for you comments. The export was made in the way you comment. Anyway, somehow I have fixed that, and now I have just 150 products, no duplications.
But the variations are not set, they have been lost. I don’t know if I have to modify the CSV file with some “|”.
Anyway, I will have a look at your tutorial, maybe everything comes from that issue.
Thanks a lot, Praveen.
Regards,
Alberto
