<div id="description">
  ## 描述
</div>

`JSONCompactStrings` 格式与 [JSONStrings](/zh/reference/formats/JSON/JSONStrings) 的区别仅在于：数据行输出为数组，而不是对象。

<div id="reading-data">
  ### 读取数据
</div>

使用 `JSONCompactStrings` 格式读取数据：

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

输出将为 JSON 格式：

```json theme={null}

    "meta":
    [
            {
                    "name": "date",

            },
