Questions tagged [fromjson]

The fromjson tag should be used in connection with the interpretation of a JSON string as a stringified representation of an arbitrary JSON entity, e.g. "1" as the number 1.

fromjson as a function would convert a JSON string representing an arbitrary JSON document to the corresponding JSON value, e.g "1" to the number 1, "[1]" to the array [1], and so on.
