JSON Functions

JSON Format

JSON is a language-independent data format that represents data as human-readable text. A JSON text can represent a number, a boolean, a string, an array, an object, or a null, with slightly different grammar. For instance, a JSON text representing a string must escape all characters and enclose the string in double quotes, such as "123\n", whereas a JSON text representing a number does not need to, such as 123. A JSON text representing an array must enclose the array elements in square brackets, such as [1,2,3]. More detailed grammar can be found in this JSON introduction.
