Add new tab viz csv

Hi Guys

Using WP Allimport/Export
I update my database with new products using WP Allimport
How can i add a new tab this way? Currently on an export and viewing the column _yikes_woo_product_tabs the info in the cells in the column look like this for example “s:14:”a:1:{i:0;b:0;}”;” Now that is fine for reimporting, but how do i add a tab using csv

Any help greatly appreciated>
Many thanks
Patrick
