Hello FabioNicc,
we prepared a localization demo for you. Here is how you can set the messages property:

grid.messages = {
        'en': {
            'columnMenuItemSortAsc': 'Sort {{mode}}',
            'columnMenuItemSortDesc': 'Sort {{mode}}', //Sort A → Z
            'columnMenuItemRemoveSort': 'Remove Sort',
            'currencySymbol': '£',
        },
        'de': {
            'columnMenuItemSortAsc': 'Sortieren {{mode}}',
            'columnMenuItemSortDesc': 'Sortieren {{mode}}',
            'columnMenuItemRemoveSort': 'Sortierung entfernen',
            'currencySymbol': '€',
        },
    };

and by switching the “locale” property, you can change the language code:

grid.locale = 'de';

grid.locale = 'en';

We also implemented two format functions. The first one translates the month of the date, and the second one switch the currency symbol according to the selected language.
Here is the index.htm file for the demo:
