Hi FlyKick
I think I made it!
Add a custom column with below code:
let typeList = [types], typeCount = List.Count([types]) in Text.Combine(List.Transform(List.Numbers(0, typeCount, 1), each Record.Field(typeList{_},"Name")), ", ")Attached the complete M code for your reference.
let Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUXJycgKSlgZKsTrRSkZAppeXF5A0twQLGAOZjo5AwsQMzDcBMr29vYGkkYVSbCwA", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Id = _t, Name = _t, Value = _t]), SourceToList = {Table.ToRecords(Source),Table.ToRecords(Table.RemoveFirstN(Source,1)),{}}, #"Converted to Table" = Table.FromList(SourceToList, Splitter.SplitByNothing(), null, null, ExtraValues.Error), #"Renamed Columns" = Table.RenameColumns(#"Converted to Table",{{"Column1", "types"}}), #"Added Custom1" = Table.AddColumn(#"Renamed Columns", "Custom", each let typeList = [types], typeCount = List.Count([types]) in Text.Combine(List.Transform(List.Numbers(0, typeCount, 1), each Record.Field(typeList{_},"Name")), ", ")) in #"Added Custom1"Let me know if you have any questions.

5 years agoJust a quick update, I have managed to get part of the way there with the following expression.
if List.Count([types]) > 0 then List.Select([types], each Record.FieldNames(_){1} = "name"){0}[name] else ""
My only issue now is looping through all the records. The above seems to only return the name of the first record in the list. Records 2 and 3 are ignored.
