【问题描述】：
我正在使用this 脚本将 Google 表格导出为 JSON 文件，它运行良好。然而，在我的工作表中，我使用了“qwe_qwe”这样的名称，并且当我将其导出为“qweqwe”时。是否可以以某种方式以原始格式导出文件。
我相信“var FORMAT_PRETTY = 'Pretty';”有所作为，但是没有这个变量我无法让它工作。
UPD：发现这个函数if (!isAlnum_(letter))检查字母数字字符，所以我决定像if (!isAlnum_(letter) && !isAlnum_("_"))这样添加smthng，但是它不起作用。

}【问题讨论】：
-
如果参数包含下划线
_，您是否尝试将函数isAlnum_更改为返回true？像这样： function isAlnum_(char) { return char >= 'A' && char = 'a' && 字符 -
行得通，正确。谢谢
