    Since it's a record column, I think you'd use Record.FieldNames instead.

     

    Maybe like this:

    [...]
    #"Custom items" = Table.ExpandListColumn(#"Removed Columns", "data"),
    ColumnList = Record.FieldNames(#"Custom items"{0}[data]),
    #"Expanded data" = Table.ExpandRecordColumn(#"Custom items", "data",
        ColumnList, List.Transform(ColumnList, each "data." & _))
in
    #"Expanded data"

Not totally clear on your scenario, but you can use Table.ColumnNames() on your [data] column to dynamically generated a list of the column names and use that in place of the hard-coded list.
