Hello all, i want to generate ngrams for the tokens in process documents from data operator. I am giving json file using read document and then converting it to data using json to data operator. But I have trouble giving the data into process documents because the converted example set has attributes types nominal,integer and so on. Please help me how can I give it to process documents from data operator?

Could you share some (small) examples, and elaborate a bit on what you would want to see as a result?
