Direct question: What is the best way to save a JSON file locally and how to do it?

Details: I have a web application that receives user data using the Facebook API (Javascript SDK), I need to save this data in a JSON file locally. After saved, step to the application written in C link that will open and interpret this JSON so that the data is saved in a database (Sqlite3).

If you are looking for a client-side solution only, one option is Localstorage.

var objteste = { 'um': 1, 'dois': 2, 'tres': 3 };

// Armazena no LocalStorage
localStorage.setItem('objteste', JSON.stringify(objteste));

// Obtém do LocalStorage
var objSalvo = localStorage.getItem('objteste');

console.log('objSalvo: ', JSON.parse(objSalvo));

However you mention database - which implies a web service. In C#, for example, you can serialize an object and use the Filesystem as a cache before sending it to the database:

var _data = new 
{
    um = 1,
    dois = 2,
    tres = 3
};

string json = JsonConvert.SerializeObject(_data);

System.IO.File.WriteAllText (@"C:\objeto.json", json);

Sources: 1, 2.
