json to map()
This function can convert a JSON string into a map.
However, only elements/structures of the JSON string are transferred to the map that can be clearly mapped there. Note: This primarily concerns simple data types from objects, see first example.
If the function is successful, the return value is true, otherwise it is false (e.g. if an incorrect JSON string was specified in a).
