When I say "Working", I mean when I try to use it, nothing happens. Here is the contents of the json.

 

{
    "type": "crafting_shapeless",
    "ingredients": [
        {
            "item": "minecraft:wool", "data": 0
        }
    ],
    "result": {
        "item": "minecraft:string",
        "count": 4
    }
}

Any suggestions?

You need to add minecraft to your recipe type because now it searches for the recipe type "YOURMODID:crafting_shapeless". Also an error should be printed in the console when starting the game.

That did the trick. Thanks!
