  ## 説明
</div>

`JSONCompactEachRow` フォーマットとの違いは、[TabSeparatedWithNamesAndTypes](/ja/reference/formats/TabSeparated/TabSeparatedRawWithNamesAndTypes) と同様に、カラム名と型を含む2つのヘッダー行も出力することです。

  ### データの挿入
</div>

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

```json theme={null}
["date", "season", "home_team", "away_team", "home_team_goals", "away_team_goals"]
["Date", "Int16", "LowCardinality(String)", "LowCardinality(String)", "Int8", "Int8"]
["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"]

```

データを挿入します:

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

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

データを読み取るには、`JSONCompactStringsEachRowWithNamesAndTypes` フォーマットを使用します。

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

出力はJSONフォーマットです：

```json theme={null}
