NPL Text which is a JSON

Hi, I have a text field that I am quite sure is a JSON object (I use it as a JSON in the frontend).

How can I use or parse this object in NPL? Is there any chance that there is a Text.toJson() function that returns a Map<Text, Text> or Optional<Map<Text, Text>>?

How could I actually have the full object somehow? Do I need to know the full at compile time?
