(Node.js) JSON Hex Encoding

See more JSON Examples

Let's say your JSON contains content that is hex encoded like this: \u05d1\u05d3\u05d9\u05e7

This example shows how to get the decoded string.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOSX, and ARM

var os = require('os');
if (os.platform() == 'win32') {  
    if (os.arch() == 'ia32') {
        var chilkat = require('@chilkat/ck-node21-win-ia32');
    } else {
        var chilkat = require('@chilkat/ck-node21-win64'); 
    }

function chilkatExample() {

    var s = "{ \"example\": \"\\u05d1\\u05d3\\u05d9\\u05e7\" }";

    var json = new chilkat.JsonObject();

    var success = json.Load(s);

    // When getting the member data, it is automatically decoded.
    console.log("member data: " + json.StringOf("example"));

    // Output:
    // member data: בדיק

    // When getting the full JSON, it remains encoded. This is expected and intentional.
    console.log("full JSON: " + json.Emit());

    // Output:
    // full JSON: {"example":"\u05d1\u05d3\u05d9\u05e7"}

    // To get the full JSON without the encoding, you can decode manually.
    var sb = new chilkat.StringBuilder();
    json.EmitSb(sb);
    // The hex encoding used by JSON is utf-8.
    sb.Decode("json","utf-8");

    console.log(sb.GetAsString());

    // Output:
    // {"example":"בדיק"}
