Exporting data from odoo isnt that hard. Now you have mentioned that this export should be imported in Italy, but the country doesnt matter too much, what matters is the format of the data that you are going to need there. Finding a module in apps.odoo.com would be the best, and if you are a developer you can make a module which would export the data. Just initialize an empy dict before you start the for loop, then assign all the values that you are going to need from the record and then return those values. Exporting data from a product would be like this:

@api.one

def get_product_data(self):

aValues = dict()

aValues['id'] = self.id

aValues['name'] = self.name

aValues['cost'] = self.standard_price

aValues['price'] = self.list_price

aValues['available'] = 1 if self.active else 0

aValues['isbn'] = self.hs_code

aValues['barcode'] = self.barcode

aValues['internal_reference'] = self.default_code

aValues['stock'] = self.qty_available

aValues['description'] = self.description_sale

return aValues

Then just write aValues into an xml or which ever filetype or extension that you need. For more info reply. Cheers
