Converting Nested Arrays in JSON with Name/Value to a Table

Having read through many of the related posts/ I still can't get from A to B... I seem to get partially there (e.g. Table of RowNum, or columns of Name-Vaue but can't get it in to the table format I want. It seems really basic but I have missed something.

JSON Sample source

{
"dataset":
[{"rowNum":"1","row":
[{"name":"Id","value":"ABCD"},
{"name":"ThingName","value":"BERT"},
{"name":"ThingState","value":"Active"},
{"name":"ThingSize","value":"Medium"}
]},
{"rowNum":"2","row":
[{"name":"Id","value":"EFGH"},
{"name":"ThingName","value":"WILF"},
{"name":"ThingState","value":"Active"},
{"name":"ThingSize","value":"Small"}
]},
{"rowNum":"3","row":
[{"name":"Id","value":"IJKL"},
{"name":"ThingName","value":"TERRY"},
{"name":"ThingState","value":"Inactive"},
{"name":"ThingSize","value":"Medium"}
]},
{"rowNum":"4","row":
[{"name":"Id","value":"MNOP"},
{"name":"ThingName","value":"Tailor"},
{"name":"ThingState","value":"Active"},
{"name":"ThingSize","value":"Huge"}
]}
]
}

Nearest output:

Value.rowNumValue.row.nameValue.row.value

Required Output:

It has to be easier than the way I am doing this; this should be bread&butter to Power Query

let
    Source = Json.Document(File.Contents("H:\DATASYNC\CyberArchitecture\Domains\Domain-Summary-Upload\sample.json")),
    #"Converted to Table" = Record.ToTable(Source),
    #"Expanded Value" = Table.ExpandListColumn(#"Converted to Table", "Value"),
    #"Expanded Value1" = Table.ExpandRecordColumn(#"Expanded Value", "Value", {"rowNum", "row"}, {"Value.rowNum", "Value.row"}),
    #"Expanded Value.row" = Table.ExpandListColumn(#"Expanded Value1", "Value.row"),
    #"Expanded Value.row1" = Table.ExpandRecordColumn(#"Expanded Value.row", "Value.row", {"name", "value"}, {"Value.row.name", "Value.row.value"}),
    #"Removed Columns" = Table.RemoveColumns(#"Expanded Value.row1",{"Name"})
in
    #"Removed Columns"
