我正在创建一个PowerBI仪表板,该仪表板显示项目和项目成员的列表。我希望列表的每一行都有一个项目,并有一个名为“ Members”的列,该列将以逗号分隔的文本形式列出成员。不幸的是,我的数据源具有作为对象数组的成员,而PowerBI似乎仅支持扩展字符串数组。
我尝试了查询编辑器和高级编辑器,但是似乎无法正确使用格式/命令。
采用JSON格式,我的数据将像这样输入:
[
{
projectName: "A",
members: [
{
firstName: "John",
lastName: "Doe"
},
{
firstName: "Jane",
lastNahe: "Doe"
}
]
}
]
我希望能够这样显示它:
| Project | Members |
---------------------------------------
| A | John Doe, Jane Doe |
有什么想法吗?看起来很简单,但是我遇到的麻烦要多得多。谢谢!

我带了您JSon文件,添加了一个额外的项目以进行正确的测试,并使用M-Query获得了您想要的结果:
let
Source = Json.Document(File.Contents("C:\yourpath\ProMem.json")),
#"Converted to Table1" = Table.FromList(Source, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Expanded Column1" = Table.ExpandRecordColumn(#"Converted to Table1", "Column1", {"projectName", "members"}, {"projectName", "members"}),
#"Expanded members" = Table.ExpandListColumn(#"Expanded Column1", "members"),
#"Expanded members1" = Table.ExpandRecordColumn(#"Expanded members", "members", {"firstName", "lastName"}, {"firstName", "lastName"}),
#"Merged Columns" = Table.CombineColumns(#"Expanded members1",{"firstName", "lastName"},Combiner.CombineTextByDelimiter(" ", QuoteStyle.None),"Name"),
#"Grouped Rows" = Table.Group(#"Merged Columns", {"projectName"}, {{"Members", each Text.Combine([Name],", "), type text}})
in
#"Grouped Rows"
