Properly load JSON file

Hi Sab ,

Maybe not the best code, but try it:

let
    Source = Json.Document(File.Contents("D:\Downloads\example.json")),
    #"Added Custom" = Json.Document(Source),
    #"Converted to Table" = Record.ToTable(#"Added Custom"),
    #"Pivoted Column" = Table.Pivot(#"Converted to Table", List.Distinct(#"Converted to Table"[Name]), "Name", "Value"),
    Header = List.Transform(#"Pivoted Column"[column_definitions]{0}, each Record.FieldNames(_){0}),
    Step1 = Table.FromList(List.Transform(#"Pivoted Column"[row_values]{0},
            each
                    Table.Transpose(Table.FromList(_, Splitter.SplitByNothing(), null, null, ExtraValues.Error))
            ), Splitter.SplitByNothing(), null, null, ExtraValues.Error),
    #"Expanded Column1" =
        Table.Combine({
                Table.Transpose(Table.FromList(Header, Splitter.SplitByNothing(), null, null, ExtraValues.Error)),
                Table.ExpandTableColumn(Step1, "Column1", {"Column1", "Column2", "Column3"}, {"Column1", "Column2", "Column3"})
        }),
    #"Promoted Headers" = Table.PromoteHeaders(#"Expanded Column1", [PromoteAllScalars=true]),
    #"Changed Type" = Table.TransformColumnTypes(#"Promoted Headers",{{"Database_RecID", Int64.Type}, {"Index_Number", Int64.Type}, {"Support_Type", type text}})
in
    #"Changed Type"
