Extract Values From a List of Records
- 4 years ago
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.

I'm guessing one or more of your Lists is null, so you can wrap that expression with try ... otherwise like this
= try List.Select([types], each Record.FieldNames(_){0} = "name"){0}[name] otherwise null
FYI that Record.FieldNames returns a list with the field names and {0} gets the first one. The {0}[name] at the end gets the first (and only) element of the selected list and the value in the [name] field.

Hi Pat,
So is it possible to get all of the names and then return a list that we can then convert to text using text.combine? I am trying to extract all the clients types not just the first one. So this works if the client has just one tag but if they have many it only gets me the first.
