# JSONCompact

Differs from JSON only in that data rows are output in arrays, not in objects.

Example:

```json
{
        "meta":
        [
                {
                        "name": "SearchPhrase",
                        "type": "String"
                },
                {
                        "name": "c",
                        "type": "UInt64"
                }
        ],

        "data":
        [
                ["", "8267016"],
                ["bathroom interior design", "2166"],
                ["yandex", "1655"],
                ["spring 2014 fashion", "1549"],
                ["freeform photos", "1480"]
        ],

        "totals": ["","8873898"],

        "extremes":
        {
                "min": ["","1480"],
                "max": ["","8267016"]
        },

        "rows": 5,

        "rows_before_limit_at_least": 141137
}
```

This format is only appropriate for outputting a query result, but not for parsing (retrieving data to insert in a table).
See also the `JSONEachRow` format.
