To solve your problem you need to loop throw your json and createElement along the way.

let json = {
    "input": {
        "name": "fname",
        "type": "text",
        "placeholder": "Enter your firstname",
        "id": "fname"
    },
    "button" : {
        "name": "btn",
        "class": "save",
        "type": "submit",
        "id": "btn1",
        "text": "save"
    }
}

Object.keys(json).forEach( (element) => {
    let foo = document.createElement(element)

    Object.keys(json[element]).forEach( (nestedAttribute) => {
        foo.setAttribute(nestedAttribute, json[element][nestedAttribute]);
    })
    document.body.appendChild(foo)
})

Object.keys(json) allow you to get the keys of your json

This way the result looks like this:

Have a nice day !
