CSV importation and problem with " for product_params in products table

[joomlaforever]

hi
VM2, M version/J17
when we look an example of field product_params in products table, we can see after exportation from phpmyadmin (CSV format):
min_order_level=s:1:"0";|max_order_level=s:1:"0"; ...

When i want to export my csv table (300 products) after filling it, there is an error :
Nombre de colonnes invalide dans les données CSV à la ligne 2.

the error comes from the character "
a solution for phpmyadmin or other  when we want to export 1000 products? thx
