Answer 1

You have to parse that string to get a valid JSON object.

Try,

var xObj = JSON.parse(xString);
console.log(xObj.Table1[0].ActualDate);

where xString is the string variable contains your JSON string.

Answer 2

If it is a string, you should make it as a json object using

var data= jQuery.parseJSON(data); 

After that can use it like.

 alert(data.Table1[0].ActualDate);

If it is an abject already, you dont have to use the jQuery.parseJSON() method

Answer 3

Since your Table1 array may grow, I would suggest you to go for iteration like

var tab = JSON.parse("you object");
for (i = 0; i < tab["Table1"].length; i++) {
    console.log(tab["Table1"][i].AccountName);
}

Answer 4

var jObj = JSON.parse(jsonString); // Converts the string to JSON object

if(jObj !== undefined && jObj.Table1 !== undefined) {
    for (i = 0; i < jObj.Table1.length; i++) {
        console.log(jObj.Table1[i].ActualDate); 
    }
}

Answer 5

You can use:

$.each(json.Table1, function(x, contents) {
    alert(contents.ActualDate);
});
