Best json beautifier

Free resourses to convert your minified JSON code into human readable and understandable format.

Json is an open-source file format that uses human-readable text to transmit data objects that consist of pairs of value-attributes and array data types (or any other serializable value). It is a very common data format used for asynchronous communication between browser-server, which is offered as a replacement for the well-known XML in some systems.

Format JSON With a PHP Function

function beautifier($json) {

    $result      = '';
    $pos         = 0;
    $strLen      = strlen($json);
    $indentStr   = '  ';
    $newLine     = "\n";
    $prevChar    = '';
    $outOfQuotes = true;

    for ($i=0; $i<=$strLen; $i++) {

        // Grab the next character in the string.
        $char = substr($json, $i, 1);

        // Are we inside a quoted string?
        if ($char == '"' && $prevChar != '\\') {
            $outOfQuotes = !$outOfQuotes;

        // If this character is the end of an element,
        // output a new line and indent the next line.
        } else if(($char == '}' || $char == ']') && $outOfQuotes) {
            $result .= $newLine;
            $pos --;
            for ($j=0; $j<$pos; $j++) {
                $result .= $indentStr;

        // Add the character to the result string.
        $result .= $char;

        // If the last character was the beginning of an element,
        // output a new line and indent the next line.
        if (($char == ',' || $char == '{' || $char == '[') && $outOfQuotes) {
            $result .= $newLine;
            if ($char == '{' || $char == '[') {
                $pos ++;

            for ($j = 0; $j < $pos; $j++) {
                $result .= $indentStr;

        $prevChar = $char;

    return $result;
