List columns simultaneous expansion

Hello Anonymous 

 

check out this solution. It adds a new column to your data, creating a table out of your year and count column. After that the list-columns are deleted and the new table expanded

let
    Source = #table({"Ref", "Year", "Count"}, {{"181", {"2019", "2020"}, {"50000", "34000"}},{"182", {"2019", "2020"}, {"50000000", "34000000"}}}),
    AddTable = Table.AddColumn
    (
        Source,
        "TableYearCount",
        each Table.FromColumns({_[Year], _[Count]}, {"Year","Count"}),
        type table
    ),
    RemoveYearCount = Table.RemoveColumns(AddTable,{"Year", "Count"}),
    ExpandYearCount = Table.ExpandTableColumn(RemoveYearCount, "TableYearCount", {"Year", "Count"}, {"Year", "Count"})
in
    ExpandYearCount
