# JsonUtil The `JsonUtil` class provides utility methods for working with JSON data. It includes methods for converting objects to JSON, parsing JSON strings, and manipulating JSON data. ### Methods #### `toJson(object: any): JsonNode` Converts a JavaScript object to a JSON representation and returns a `JsonNode` object. ```typescript // Convert an object to JSON var dataObject = { "name": "John", "age": 30 }; var jsonData = JsonUtil.toJson(dataObject); ``` *** #### `parse(jsonStr: String): JsonNode` Parses a JSON string and returns a `JsonNode` object representing the parsed JSON data. ```typescript // Parse a JSON string var jsonString = '{"name": "Alice", "age": 25}'; var parsedData = JsonUtil.parse(jsonString); ``` *** #### `parseXml(xmlStr: String): JsonNode` Parses a XML string and returns a `JsonNode` object representing the parsed XML data. {% code overflow="wrap" %} ```typescript // Parse a XML string var xmlStr = "ToveJaniReminderDon't forget me this weekend!JaniToveRe: ReminderI will not" var obj = JsonUtil.parseXml(xmlStr) var note0 = obj.get("note").get(0); var note1 = obj.get("note").get(1); var note1ID = note1.get("id").asInt() // 502 var note1Body = note1.get("body").asText(); // I will not ``` {% endcode %} *** #### `stringify(jsonNode: JsonNode): String` Converts a `JsonNode` object back to a JSON string. ```typescript // Stringify a JsonNode var jsonString = JsonUtil.stringify(jsonData); ``` *** #### `prettyPrint(jsonNode: JsonNode): String` Formats and pretty-prints a `JsonNode` object as a JSON string with proper indentation and line breaks. ```typescript // Pretty print a JsonNode var prettyJsonString = JsonUtil.prettyPrint(parsedData); readPath(jsonNode: String, path: String): any Reads a specific value from a JSON object using a JSON path and returns it. // Read a value from JSON using a pathvar jsonContent = '{"person": {"name": "Bob", "address": {"city": "New York"}}}';var city = JsonUtil.readPath(jsonContent, "person.address.city");return "City: " + city; // City: New York ``` *** #### `readPath(jsonNode: String, path: String): any` Reads a specific value from a JSON object using a JSON path and returns it. ```typescript // Read a value from JSON using a path var jsonContent = '{"person": {"name": "Bob", "address": {"city": "New York"}}}'; var city = JsonUtil.readPath(jsonContent, "person.address.city"); return "City: " + city; // City: New York ``` *** #### `createObjectNode(): ObjectNode` Create an empty Json Object to be set with values. ```typescript // Create an empty Json Object var objectNode = JsonUtil.createObjectNode(); // Using the object objectNode.put("doubleKey", Double.parseDouble("553.1")); objectNode.put("str", "This is a string"); objectNode.put("int", Integer.sum(4, 5)); objectNode.set("jsonObject", JsonUtil.toJson(Instant.now())); return objectNode; ``` *** ### Examples **Example: JSON Read Using JSON Path** **Description:** This script reads a JSON property value using JSON path from a JSON string. **Use Case:** Useful for extracting specific data from structured JSON objects. ```javascript // Reads the signature filename from a json string var jsonString = '{"signature":{"fileName":"mySignature.jpg"}}'; var signatureFileName = JsonUtil.readPath(jsonString, "$.signature.fileName"); ```
