Anha!! actually I have a PHP Class which works pretty well with same json object key (you are using here diffrent json key in third set). So, if you like then you can modify my PHP Export Class as you want (for different object key). Here I am going to explain example and going to share my class with you too. Hope, after modify this class your wish come true :)
PHP Export Class [Class.Export.php]
<?php

Okay, here is HTML and PHP Code to demonstrate how it works.
HTML Code:
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>JSON to Excel POC</title>
<script type="text/javascript">
<!--
function excelExport() {
// this is your json data as string or you can
// use as object too
var jsonObject = '[{ "Comment" : "Good", "ExperinceMonths" : "4", "ExperinceYears" : "4", "Score" : "3", "Subject" : "CPP", "Topic" : "Scripting (mention details)" }, { "Comment" : "Excilent", "ExperinceMonths" : "6", "ExperinceYears" : "6", "Score" : "6", "Subject" : "CSharp", "Topic" : "WPF" }]';
// create a form
var form = document.createElement('FORM');
form.name = 'exportform';
form.id = 'exportform';
form.method = 'POST';
form.action = './export.php';
// create a hidden input inside form
var hiddenInput = document.createElement('INPUT');
hiddenInput.type = 'HIDDEN';
hiddenInput.name = 'exportdata';
hiddenInput.id = 'exportdata';
hiddenInput.value = jsonObject;
// insert hidden element inside form
form.appendChild(hiddenInput);
// insert form inside body
document.body.appendChild(form);
// submit the form
form.submit();
// remoce the form
document.body.removeChild(form);
return true;
}
//-->
</script>
</head>
<body>
<input type="button" value="Export" onClick='excelExport(); return false;'>
</body>
</html>
and finally Here is
PHP Code [export.php]
<?php
// add Class Export File
require_once 'Class.Export.php';
// make a new onject of Class Export
$export = new Export ();
// Send POSt data to make
// Excel File
if(isset($_POST['exportdata'])){
$export->saveAsExcel();
}
?>
Hope, this chunk of code will help people Because, Sharing is always Caring :) Cheers!!
