Hi subrisi,
You’ve convinced me to give WP All Import a try. I had some isses with Woo product variations and I asked Louis to send me a demo CSV file with product variations in order to properly understand. I was surprise to read from him that he was not sure how variations work in WooCommerce and that I should find out from WooThemes what fields must be set for a product to be considered a variation.
I would really apreciate If you could give me a hint how to proceed.
Kind regards
