Change a given string that contains hash inside it to a hash object. Similar to eval(string_with_hash)

string with hash to hash

def convert_to_hash(string)
    string.gsub(/[{}:]/,'').split(', ').inject({}) do |hash, str_value|
      splitted_value = str_value.split('=>')
      splitted_value.delete('')
      key,value = splitted_value

      if splitted_value.count > 2
        new_str = str_value.split(key)
        new_str.delete('')
        value = convert_to_hash(new_str.last.to_s)
      end

      key.tr!('"', '')
      value.tr!('"', '')
      hash[key] = value
      hash
    end
  end
