Hi Nilambar, thank you for your answer.
But I’m not moving the books from a wordpress website to another. The old website is old technology, so I’m taking all information about the books – 600 of them! – into a csv file. I know that most information – for example the name, price, atributes – can be imported to the import on the products of wordpress if I follow a specific columns naming. I was wondering if I can also import the tab information, specifying some columns with that information on the csv. Otherwise I have to manually input the information on the 3 tabs I want (synopsis, index and special information) manually on the wordpress panel – after importing everything except that trough the csv. But I have 600 books! That’s a ton of work!!
