Pretty Print JSON (Formatter, Beautifier)

Demonstrates how to emit JSON in a pretty, human-readable format with indenting of nested arrays and objects.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

JavaScript

var success = false;

var json = new CkJsonObject();

var jsonStr = "{\"name\": \"donut\",\"image\":{\"fname\": \"donut.jpg\",\"w\": 200,\"h\": 200},\"thumbnail\":{\"fname\": \"donutThumb.jpg\",\"w\": 32,\"h\": 32}}";

success = json.Load(jsonStr);
if (success !== true) {
    console.log(json.LastErrorText);
    return;
}

// To pretty-print, set the EmitCompact property equal to false
json.EmitCompact = false;

// If bare-LF line endings are desired, turn off EmitCrLf
// Otherwise CRLF line endings are emitted.
json.EmitCrLf = false;

// Emit the formatted JSON:
console.log(json.Emit());
