Clean Code in export CSV

Hello;

First of all, thank you for this excellent plugin.

Is there any way to clean up the code when doing a CSV export in woocommerce?

For exemple
a:2:{i:0;a:3:{s:5:"title";s:17:"Caractéristiques";s:2:"id";s:16:"caracteristiques";s:7:"content";s:352:"

A GREP or PHP function maybe ?
