したがって、基本的には次のような構造になります。

{
    "i$tems": {
        "it$em": [
            {
                "batt$ers": {
                    "ba$tter": [
                        {
                            "i$d": "1001",
                            "t$ype": "Regular"
                        },
                        {
                            "i$d": "1002",
                            "type": "Chocolate"
                        },
                        {
                            "i$d": "1003",
                            "t$ype": "Blueberry"
                        },
                        {
                            "i$d": "1004",
                            "t$ype": "Devil's Food"
                        }
                    ]
                },
                "$id": "0001",
                "$name": "Cake",
                "$ppu": 0.55,
                "$topping": [
                    {
                        "i$d": "5001",
                        "t$ype": "None"
                    },
                    {
                        "i$d": "5002",
                        "t$ype": "Glazed"
                    },
                    {
                        "i$d": "5005",
                        "t$ype": "Sugar"
                    },
                    {
                        "i$d": "5007",
                        "t$ype": "Powdered Sugar"
                    },
                    {
                        "i$d": "5006",
                        "t$ype": "Chocolate with Sprinkles"
                    },
                    {
                        "i$d": "5003",
                        "t$ype": "Chocolate"
                    },
                    {
                        "i$d": "5004",
                        "t$ype": "Maple"
                    }
                ],
                "ty$pe": "donut"
            }
        ]
    } 
}

そして、このようなものが欲しい：

    "items": {
        "item": [
            {
                "batters": {

基本的に私はこのコードを思いつきました：

#!/usr/bin/env ruby

require 'yaml'
require 'json'

def iterate(data)
  if data.is_a?(Array)
    return data.map { |i| iterate(i) }
  elsif data.is_a?(Hash)
    new_h = Hash[data]
    data.each do |k, v|
      if k =~ /\$/
        new_key = k.delete("\$")
        new_h.delete(k)
        if v.is_a?(Array) || v.is_a?(Hash)
          new_h[new_key] = iterate(v)
        else
          new_h[new_key] = v
        end
      else
        if v.is_a?(Array) || v.is_a?(Hash)
          new_h[k] = iterate(v)
        else
          new_h[k] = v
        end
      end
    end
    return new_h
  end
end

data = YAML.load(File.read('nested.json'))
puts JSON.dump(iterate(data))
