let
Source = Json.Document(File.Contents("D:\Downloads\example.json")),
#"Added Custom" = Json.Document(Source),
row_values = #"Added Custom"[row_values],
#"Converted to Table" = Table.FromList(row_values, Splitter.SplitByNothing(), null, null, ExtraValues.Error),
#"Extracted Values" = Table.TransformColumns(#"Converted to Table", {"Column1", each Text.Combine(List.Transform(_, Text.From), ";"), type text}),
#"Split Column by Delimiter" = Table.SplitColumn(#"Extracted Values", "Column1", Splitter.SplitTextByDelimiter(";", QuoteStyle.Csv), {"Column1.1", "Column1.2", "Column1.3"}),
#"Changed Type" = Table.TransformColumnTypes(#"Split Column by Delimiter",{{"Column1.1", Int64.Type}, {"Column1.2", Int64.Type}, {"Column1.3", type text}})
