（非数据库专家试图做数据库的事情）
场景：使用从Podio应用程序复制的数据将Azure DB数据源输入到MSFT PowerBI（如果您有更简便的方法，请告诉我）。在PowerBI中-我无法正确解析JSON列。这是我的位置：
在Power Query Editor中分析该列，我得到一个List值Step 1: Parse JSON Column
将已解析的列扩展到新行，它返回记录Step 2: Expand to New Rows
扩展列以显示标签和值，返回列表Step 3: Expand Column (label/values elements)
Expanded Fields.values（期望它们全部显示出来，获取记录）Step 4: Expand Fields.values
提取值（获取而不是全部）Step 5: Extract Values
这是我无法通过的地方。我已经查看了一些类似的帖子和尝试的路径（“新建查询” /将记录添加为新表），但没有成功。请让我知道是否有人可以提供帮助:)

这是由于JSON的模式所致。查看$[*].values[*].value的每个条目时，它可以是字符串或对象。看起来当$[*].type是“文本”时，它是一个字符串，而当它是另一个值（例如“联系人”，“类别”或“应用”）时，它是一个对象。
因此，根据您的要求，您可以使用Table.SelectRows从输出中除去对象条目，或者使用Table.TransformColumns将它们转换为表示对象的某些String值。
