<script type="text/javascript">
    function initialize() {
        var markers = JSON.parse('[{"title":"Chennai","lat":"12.897400","lng":"80.288000","Description":"welcome to chennai"},{"title":"Hyderabad","lat":"17.266700","lng":"78.530200","Description":"welcome to hyderabad"},{"title":"Banglore","lat":"12.897400","lng":"77.519500","Description":"welcome to Banglore"},{"title":"vishkapatnam","lat":"17.518300","lng":"83.320300","Description":"welcome to Vishkapatnam"}]');

            center: new google.maps.LatLng(markers[0].lat, markers[0].lng),
            zoom: 5,
            mapTypeId: google.maps.MapTypeId.ROADMAP

        };

I am getting the JSON is not find Microsoft?so what do i do?

That's very strange, in IE8 it should be already fully supported, anyway read here: http://stackoverflow.com/questions/4908875/is-json-parse-supported-by-all-major-browsers — Niccolò Campolungo, Sep 26 '13 at 09:00
Almost certain to be caused by IE8 in compatibility mode (or quirks mode). — Spudley, Sep 26 '13 at 09:04

Check to see if you are in compatibility mode. You can ensure that IE8 is not rendering in IE7 mode via a meta tag

<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />

or preferably, using the doctype

<!DOCTYPE html>

Somewhere before your code :

window.JSON || 
    document.write('<script src="https://cdnjs.cloudflare.com/ajax/libs/json3/3.2.4/json3.min.js"><\/script>');
