Datasets json columns

🤗Datasets

I’m noticing some datasets have the columns as json in the dataviewer e.g. midas

Would you know how is that generated? so far in python, creating a .jsonl file results in the columns being stored(saved before pushed to hugging hub) as strings.

So how can i get them in that format of a json. It is nice to be consistent .

Thanks

it needed json.dumps to get the columns as json type (on creating the jsonl file)… !
