Review comment:
       But if the input is a list, wouldn't it be converted to a 2-dimensional list?
   ```
   self.source_objects = "file1.csv"
   source_object = [self.source_objects]
   output: ["file1.csv"]
   
   self.source_objects = ["file1.csv", "file2.csv", "file3.csv"]
   source_object = [self.source_objects]
   output: [["file1.csv", "file2.csv", "file3.csv"]]
   ```
