List columns simultaneous expansion

[Anonymous]

Hello Community,

First of all, I hope all of and your families are safe during this period.

I would appreciated it if you could help me with the below task.

I have a table that includes two list columns.

After expanding the Lists, I get the below result.

I want to expand the "Year" column and then, to expand the "Count" column in such a way that it will result in something like the below table (the "Count" column will include the correct value per "Year" per "Ref").

Any help would be hugely appreciated.

Kind regards,

George

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

Copy paste this code to the advanced editor in a new blank query to see how the solution works.

Thank you Jimmy,

This worked just fine!!!

The code I used is 

= Table.AddColumn(#"Renamed Columns", "TableYearCount",each Table.FromColumns({_[Year],_[Count]},{"Year","Count"}),type table)

, where #"Renamed Columns" is the previous applied step.

It also took me a while to figure out that in order for this to work, the lists must not be expanded.

Kind regards,

George
