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.

// 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.

// Parse a JSON string
var jsonString = '{"name": "Alice", "age": 25}';
var parsedData = JsonUtil.parse(jsonString);

stringify(jsonNode: JsonNode): String

Converts a JsonNode object back to a JSON string.

// 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.

// 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 path
var jsonContent = '{"person": {"name": "Bob", "address": {"city": "New York"}}}';
var city = JsonUtil.readPath(jsonContent, "person.address.city");
return "City: " + city; // City: New York

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.

// Reads the signature filename from a json string
var jsonString = '{"signature":{"fileName":"mySignature.jpg"}}';
var signatureFileName = JsonUtil.readPath(jsonString, "$.signature.fileName");
