        "country": "Austria",
        "currency": "$41.75"
    },
    {
        "text": "nec orci. Donec nibh. Quisque nonummy ipsum non arcu. Vivamus",
        "country": "Austria",
        "currency": "$44.69"
    },
    {
        "text": "penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec",
        "country": "Singapore",
        "currency": "$71.20"
    },
    {
        "text": "dictum sapien. Aenean massa. Integer vitae nibh. Donec est mauris,",
        "country": "Costa Rica",
        "currency": "$26.40"
    },
    {
        "text": "feugiat metus sit amet ante. Vivamus non lorem vitae odio",
        "country": "United States",

Simply copy and paste it into the box and then click minify. The result should be as below:
