Hello -- Is there a way to load a JSON from a file.

I have a "JSON" file which has a sting 1035164 long with the following format: 

[
    {
        "id": "12345",
        "title": "John Smith",
        "image_uri": "https://<some URL>",
        "image_timestamp": "1496781334",
        "image_url":"https://<some URL>",
        "is_restricted_under_18_only": false,
        "is_restricted_adult_only": false
    },
.
