let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMlTSUfJNLErNVorViVYygvF0FKCUV2J2aRJYzgQoB+ZhkTOHyYF5hgZAbkBiWX4OhGuMyjUFcoPz8xIhNhpAeToKEDIgtSS1CCIFchuYi0XOGCEHpYCOKsnMU4qNBQA=", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Row = _t, Input = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Row", Int64.Type}, {"Input", type text}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 0, 1, Int64.Type),
    #"Added Custom" = Table.AddColumn(#"Added Index", "Result", each List.Accumulate({0..[Index]},"",(state,current)=>
let p = Text.PositionOf(#"Added Index"[Input]{current},state)
in if p=-1 then #"Added Index"[Input]{current} else Text.RemoveRange(#"Added Index"[Input]{current},p,Text.Length(state))),type text),
    #"Replaced Value" = Table.ReplaceValue(#"Added Custom",each [Result],each if Text.StartsWith([Result],", ") then Text.RemoveRange([Result],0,2) else [Result],Replacer.ReplaceValue,{"Result"})
in
    #"Replaced Value"
