For security, you can't write on client's disk.
The best way to save localy is to use localStorage.
You shoul read that page from MDN about webStorage.
some samples here.

var myContent = 'I am the content to save';
localStorage.setItem('mySaved', myContent);

and later to retrieve it :

 var myContent = localStorage.getItem('mySaved');

you can't write a JSON to a file on the clientside due to security reasons. (Otherwise you have access to the filesystems of your website's users.) You would have to use a server-side language for this, and store the file on the server-side.
