Fiddle used to be able to generate data dynamically doing something like:

Code:
{
    "success": true,
    "total": 1000,
    "users": [
        {{#repeat 1000}}
        {
            "id": {{@index}},
            "name": "{{firstName}} {{lastName}}",
            "email": "{{email}}"
        }
        {{/repeat}}
    ]
}
This is no longer working. Here's a fiddle that was created 3 years ago that used to work:
