IMTECH SOLUTIONS, I hope you see this (I can't comment on your text, since I don't have enough karma points). 

I gave up on using connector_importer. Instead I used this: https://github.com/tfrancoi/odoo_csv_import

Hope this helps. If you need details, tell me. 

Hi,

Have you succeeded to get an example of use of this tool? could you share please?

Regards,

Hi Edi: Odoo has built-in import functionality for something like this. You can define a custom menu item and link it to a window action based on the custom model you defined.
