    Here's one way to do it in the query editor.  To see how it works, just create a blank query, open the Advanced Editor and replace the text there with the M code below.

     

    let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtTTM60xNNDTMzStMQJSxgZKsTpAYQOQkBFIDMgwMoSIGoPoWAA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [ListsAsText = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ListsAsText", type text}}),
    #"Added Custom" = Table.AddColumn(#"Changed Type", "Custom", each List.Combine(List.Transform(Text.Split([ListsAsText], "|"), each Expression.Evaluate("{"&_&"}")))),
    #"Expanded Custom" = Table.ExpandListColumn(#"Added Custom", "Custom")
in
    #"Expanded Custom"
