abc ['A', 'B'] => abc ['A', 'B']
def C def ['C']

,
So you only need to handle the single string e.g convert C to ['C'] if it already starts with [ then do nothing.First thing that comes to mind would be using a formula :
if(startsWith(new_column, "['"),new_column, concat("['",new_column,"']"))
Let me know if that works for you.

Hi @RohitRanga
,Not sure I fully understand the transformation you are looking for, are you looking to convert C to an array?
We do have the following processor which does what you are looking for :

Let me know if that helps.

Thanks the response! Let me clarify my question:
I have a classification dataset with a label/class column. This column has either a list of strings or a single string. I want to make it uniform by converting those single string rows into a list with one string. Is this clear now? -
Wow, I was not aware that we could do this. Thanks a lot @AlexT
