This example applies convert.case to each string in a list, where the wrangle would not normally operate on the list as a whole.

wrangles:
  - accordion:
      input: list_column
      output: modified_lists
      wrangles:
        - convert.case:
            input: list_column
            output: modified_lists
            case: upper

list_column
["a", "b", "c"]
["e", "f", "g"]

modified_lists
["A", "B", "C"]
["E", "F", "G"]
