    Hi,

    This M code works

    let
    Source = Excel.CurrentWorkbook(){[Name="Table1"]}[Content],
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"ID", Int64.Type}, {"Name", type text}, {"Name 2", type text}, {"Date", type text}, {"Detail", type text}, {"Rank 1 ", Int64.Type}, {"Rank 2", Int64.Type}, {"Rank 3", Int64.Type}, {"Category", type text}, {"Movement", type text}}),
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 1, 1),
    #"Unpivoted Other Columns" = Table.UnpivotOtherColumns(#"Added Index", {"Index"}, "Attribute", "Value"),
    Partition = Table.Group(#"Unpivoted Other Columns", {"Index"}, {{"Partition", each Table.AddIndexColumn(_, "Index1",1,1), type table}}),
    #"Expanded Partition" = Table.ExpandTableColumn(Partition, "Partition", {"Attribute", "Value", "Index1"}, {"Attribute", "Value", "Index1"}),
    #"Pivoted Column" = Table.Pivot(Table.TransformColumnTypes(#"Expanded Partition", {{"Index", type text}}, "en-IN"), List.Distinct(Table.TransformColumnTypes(#"Expanded Partition", {{"Index", type text}}, "en-IN")[Index]), "Index", "Value"),
    #"Removed Columns" = Table.RemoveColumns(#"Pivoted Column",{"Index1"})
in
    #"Removed Columns"

    The only thing i cannot get to work here is the order of the items in the attribute column to match your order.

    Hope this helps.

    parry2k - Thanks a lot for taking a stab at this! I did the same initially, and instead of joining to the ID column, in the main table I defined an Index Column which I utilized instead to connect to the other table wherein I did the unpivoting, but this is not working as expected on my end with my entire data set. Also worth mentioning my ID is not a distinct column and each ID might have multiple rows which is the reason I defined the index column. Any other suggestions if you may have?

      nirvana_moksh using index column make sense to bring unique id. So what exactly is not working on your dataset?

        parry2k  - Using the index column for the relationship for some reason does not filter the secondary table correctly (clicking on a row on the main table shows up the "first value" of some other row). Just for the sake of it, I used the ID column and that worked, which I think is odd. In your opinion is the usage of an

        index column as a unique identifier a good approach?  Because I do use the same logic for other solutions for dynamic axis change. When I check the index column id for one row on the main table and the same for the second it matches, but the value output is not correct for some reason
