FromJson

Description

fromJson is a function that converts a JSON string to a STEP-type.

Syntax

fromJson(string json)

• json must be a string containing valid JSON.

Remarks

• any type (number, string, bool, null, list, map) can be returned
• if the JSON string is invalid, null is returned
• if the JSON string is empty, null is returned
• a JSON object is converted to a STEP map (order is not guaranteed to be preserved)
• a JSON array is converted to a STEP list (order is preserved)
• the fromJson function is the inverse of the toJson function

Examples

fromJson("{\"a\": 1, \"b\": 2}") // returns a map: {"a": 1, "b": 2}
fromJson("[1, 2, 3]") // returns a list: [1, 2, 3]
fromJson("{\"a\": 1, \"b\": 2") // returns null
