# 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");
```
