JSON Parser

Function parsing JSON strings to values

Evaluation

This expression evaluates to a function of the form:

(string x) -> any

The function is consistent with parser semantics used for string to data conversion, for example by the CSV Input step.

Processing

The JSON String x is converted into a value representing the JSON contents using the following rules:

• JSON objects are converted to dict values
• JSON arrays are converted to list values
• JSON strings are converted to string values
• JSON numbers are converted to long or double values
• JSON booleans are converted to boolean values
• JSON null is converted to nil

If x is nil, nil is returned.
