Hi there, what's the correct way to call:
after calling these JSON methods, fiddler says:
Variable 'JSON' has not been declared

You are using import because your FIddlerScript is set to use JScript.NET and not C#. The examples that Eric provided were written with C#. You can change your FiddlerScript language through Tools > Options > Scripting > Language.

Also, eric, this syntax you mention is more or less completely wrong.
1. "using Fiddler.webFormats" does not work. I had to use "import ...".
2. "Hashtable oObj" is wrong. It should be "var oObj:Hashtable ..."
3. Why Hashtable and not Object?

Your response was a bit confusing. You mention the OP's JSON object doesn't directly exist within FiddlerScript, but you then reference that object in your code. Or is it a different object?
You write "The .NET framework ... offers a variety of JSON libraries" followed by "Having said that...". Usually the latter phrase indicates that the previous sentence isn't really relevant or was a caveat which you are about to discount. The next sentence reads "Fiddler does itself have its own JSON objects". Great! The semicolon and next sentence fragment reads "they're not optimized for FiddlerScript, however". So Fiddler provides its own JSON objects to use with FiddlerScript, but they are not optimized for FiddlerScript??!?
Is there a reference somewhere to this object/class and methods? What's the converse of "ParseResult" (ie, "stringify()"?)

The JSON object you're trying to use is a part of the browser's Document Object model and doesn't directly exist within FiddlerScript. The .NET framework (on which FiddlerScript runs) offers a variety of JSON libraries and one of them may be your best choice.
Having said that, Fiddler does itself have its own JSON objects; they're not optimized for FiddlerScript, however, so you might find them a little cumbersome. At the top of your script, add:
In the code, add e.g.
var oResponseBody = oSession.GetResponseBodyAsString();
JSON.JSONParseResult oJSON = JSON.JsonDecode(oResponseBody) as JSON.JSONParseResult;
Hashtable oObj = oJSON.JSONObject as Hashtable;
var oVal = (oObj != null) ? oObj["myObjectValue"] : null;
