JSON FAQ

Usage from Address Bar

You can use direct access to this page from your browser address bar. Type the string that you need to encode or decode according to the following schema: https://md5calc.com/json/<TYPE:enc|dec>/<PHRASE> For example, to visit a page that contains encoded "hello world", you can just visit the URL: https://md5calc.com/json/enc/hello+world Another cool feature is that you can specify "json" or "plain" mode in the URL and you will get only the encoded/decoded string in response.
Schema for this feature: https://md5calc.com/json/<TYPE:enc|dec>.<OUTPUT:plain|json>/<PHRASE> Example: https://md5calc.com/json/enc.plain/hello+world Will output: "hello world"

Usage from JavaScript

We have removed the CORS restriction so you can use direct access to JSON encode/decode in your JavaScript applications via AJAX.

Example:

var toEncode = 'hello world';
var xhr = new XMLHttpRequest();
xhr.onreadystatechange = function () {
  if (xhr.readyState == 4 && xhr.status == 200) {
    console.log('Json encoded "'+toEncode+'" is "'+JSON.parse(xhr.response)+'"');
  };
};
xhr.open('GET', 'https://md5calc.com/json/enc.json/'+encodeURIComponent(toEncode), true);
xhr.send();

Keep in mind that this example makes no sense because JavaScript has built-in functions JSON.stringify() and JSON.parse(), which do the same.

Usage from PHP

You can use direct access to this function in your applications.

PHP Example:

<?php
    $str = 'hello world';
    $url ='https://md5calc.com/json/enc.plain/'.urlencode($str);
    $json = file_get_contents($url);
    echo 'Base64 of "'.$str.'" is "'.$json.'"';

Keep in mind that this example makes no sense because PHP has built-in functions json_encode() and json_decode(), which do the same.

How to do the same in PHP

<?php
    $str = '¡Hola!';
    $jsonEncodedStr = json_encode($str);
    $jsonDecodedStr = json_decode($jsonEncodedStr, true);
    echo '<pre>';
    echo $str.PHP_EOL
         .' &rarr; '.$jsonEncodedStr.PHP_EOL
         .' &rarr; '.print_r($jsonDecodedStr, true).PHP_EOL
    ;
    echo '</pre>';

How to do the same in JavaScript

var str = 'https://localhost/?param1=¡Hola!&param2=¡Hola!';
var jsonEncodedStr = JSON.stringify(str);
var jsonDecodedStr = JSON.parse(jsonEncodedStr);
console.log(str);
console.log('-> ' + jsonEncodedStr);
console.log('-> ' + jsonDecodedStr);
