[JSON](/ja/reference/formats/JSON/JSON) と異なるのは、データ行がオブジェクトではなく配列として出力される点だけです。

<div id="inserting-data">
  ### データの挿入
</div>

次のデータを含む `football.json` という名前のJSONファイルを使用します。

```json theme={null}
{
    "meta":
    [
        {
            "name": "date",
            "type": "Date"
        },
        {
            "name": "season",
            "type": "Int16"
        },
        {
            "name": "home_team",
            "type": "LowCardinality(String)"
        },
        {
            "name": "away_team",
            "type": "LowCardinality(String)"
        },
        {
            "name": "home_team_goals",
            "type": "Int8"
        },
        {
            "name": "away_team_goals",
            "type": "Int8"
        }
    ],
    "data":
    [
        ["2022-04-30", 2021, "Sutton United", "Bradford City", 1, 4],
        ["2022-04-30", 2021, "Swindon Town", "Barrow", 2, 1],
        ["2022-04-30", 2021, "Tranmere Rovers", "Oldham Athletic", 2, 0],
        ["2022-05-02", 2021, "Port Vale", "Newport County", 1, 2],
        ["2022-05-02", 2021, "Salford City", "Mansfield Town", 2, 2],
        ["2022-05-07", 2021, "Barrow", "Northampton Town", 1, 3],
        ["2022-05-07", 2021, "Bradford City", "Carlisle United", 2, 0],
        ["2022-05-07", 2021, "Bristol Rovers", "Scunthorpe United", 7, 0],
        ["2022-05-07", 2021, "Exeter City", "Port Vale", 0, 1],
        ["2022-05-07", 2021, "Harrogate Town A.F.C.", "Sutton United", 0, 2],
        ["2022-05-07", 2021, "Hartlepool United", "Colchester United", 0, 2],
        ["2022-05-07", 2021, "Leyton Orient", "Tranmere Rovers", 0, 1],
        ["2022-05-07", 2021, "Mansfield Town", "Forest Green Rovers", 2, 2],
        ["2022-05-07", 2021, "Newport County", "Rochdale", 0, 2],
        ["2022-05-07", 2021, "Oldham Athletic", "Crawley Town", 3, 3],
        ["2022-05-07", 2021, "Stevenage Borough", "Salford City", 4, 2],
        ["2022-05-07", 2021, "Walsall", "Swindon Town", 0, 3]
    ]
}
```

データを挿入します:

```sql theme={null}
INSERT INTO football FROM INFILE 'football.json' FORMAT JSONCompact;
```

<div id="reading-data">
  ### データの読み取り
</div>

`JSONCompact` フォーマットを使ってデータを読み取ります。

```sql theme={null}
SELECT *
FROM football
FORMAT JSONCompact
```

出力はJSONフォーマットです：

```json theme={null}
{
    "meta":
    [
        {
            "name": "date",
            "type": "Date"
        },
        {
            "name": "season",
            "type": "Int16"
        },
        {
            "name": "home_team",
            "type": "LowCardinality(String)"
        },
        {
            "name": "away_team",

        },
