let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WckxJzFXSUfJNzAOShgZKsTrRSi6JZZkpcEEjiGBwYlEikBeenwsWNYaI+iWWZCTmZKYiyZgAZWIB", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Name = _t, Type = _t, Value = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Name", type text}, {"Type", type text}, {"Value", Int64.Type}}),
    #"Grouped Rows" = Table.Group(#"Changed Type", {"Type"}, {{"Total", each List.Sum([Value]), type nullable number}, {"Rows", each _, type table [Name=nullable text, Type=nullable text, Value=nullable number]}}),
    #"Expanded Rows" = Table.ExpandTableColumn(#"Grouped Rows", "Rows", {"Name", "Value"}, {"Name", "Value"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Expanded Rows",{"Type", "Name", "Value", "Total"})
in
    #"Reordered Columns"
