Excel power query - Tranform JSON data correctly

I have the issue that I do not know how to transform the data correctly to get it in a table. The data is coming from an API in JSON. I can transform the data into a table, but I get for each name a column.

 

What I did:

 

First I have the records in a column

 
 

Then I expand it into a table. Thats okay so far. I tried to group then the data, but that lead to the issue that I got the number 2 in the value column for each entry, instead of the acutal data.

So I tried to tranform the the data:

 

Switched lines with columns,

The first line is the descripiton.

Unfortunately, Power Query does not recognize that the data in the same named columns should go into that.

 

I expect to have a result like this in Power Query:

How can I do this?

    in this way (almost) all done by GUI

     

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUpUitWJVjICspLALGMgKxnMMgGyUsAsQySFSCqRlELVxgIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [value = _t, name = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"value", Int64.Type}, {"name", type text}}),
    grp = Table.Group(#"Changed Type", {"name"}, {{"grp", each _[value]}}),
    #"Extracted Values" = Table.TransformColumns(grp, {"grp", each Text.Combine(List.Transform(_, Text.From), ","), type text}),
    #"Split Column by Delimiter" = Table.SplitColumn(#"Extracted Values", "grp", Splitter.SplitTextByDelimiter(",", QuoteStyle.Csv), {"grp.1", "grp.2"}),
    #"Changed Type1" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"grp.1", Int64.Type}, {"grp.2", Int64.Type}}),
    #"Transposed Table" = Table.Transpose(#"Changed Type1"),
    #"Promoted Headers" = Table.PromoteHeaders(#"Transposed Table", [PromoteAllScalars=true]),
    #"Changed Type2" = Table.TransformColumnTypes(#"Promoted Headers",{{"a", Int64.Type}, {"b", Int64.Type}, {"c", Int64.Type}, {"d", Int64.Type}})
in
    #"Changed Type2"

    Hello Anonymous 

     

    try to add a new step after your step of ExpandedList (first screenshot) like this:

    Table.FromRecords(YourStepOfExpandedList[Column1)

     

    Hope it helps

    try this scheme:

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUUpUitWJVjICspLALGMgKxnMMgGyUsAsQySFSCqRlELVxgIA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [value = _t, name = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"value", Int64.Type}, {"name", type text}}),
    grp = Table.Group(#"Changed Type", {"name"}, {{"grp", each _[value]}}),
    tfc=Table.FromColumns(grp[grp],grp[name])
in
    tfc

     

    if you have problem to adapt the code, post your table in a way that is easy to copy and some one will do it for you.
