展平Json输出

Question

如何将这些数据转换为平面数据帧？你知道吗

我试过使用json\u normalize和pivot，但似乎无法正确使用格式。你知道吗

这是我想要的输出格式：

SiteName | SiteId |…| CompressorTerrefid | TankID | TankNumber…| TankID | TankNumber…| TankID |。。。日期和时间|。。。你知道吗

请告知

在r中，您可以使用jsonlite包这样做：

result<- as.data.frame(jsonlite::stream_in(textConnection(data)))
