Данные парсинга не сохраняются в xlsx

Решил изучать парсинг. Первый мой парсер. не могу понять, почему собранные данные не сохраняются в xlsx-файл Данные собираются, в json сохраняется, а в xlsx нет. Ошибок никаких не выдает. Помогите разобраться

Вот код:

import json
import requests
import xlsxwriter
from bs4 import BeautifulSoup

OUT_FILENAME = 'out.json'
OUT_XLSX_FILENAME = 'out.xlsx'

def dump_to_json(filename, data, **kwargs):
  kwargs.setdefault('ensure_ascii', False)
  kwargs.setdefault('indent', 1)
  with open(OUT_FILENAME, 'w', encoding='utf-8') as f:
      json.dump(data, f, **kwargs)

def dump_to_xlsx(filename, data):
  if not len(data):
    return None
  with xlsxwriter.Workbook(filename) as workbook:
    ws = workbook.add_worksheet()
    headers = ['Название', 'Назв.(англ.)', 'Год выпуска', 'Страна', 'Рейтинг', 'Ссылка']
    bold = workbook.add_format({'bold': True})

    for col, h in enumerate(headers):
      ws.write_string(0, col, h, cell_format = bold)

    for item in enumerate(data, start=1):
      ws.write_string(row, 0, item['title_rus'])
      ws.write_string(row, 1, item['title_eng'])
      ws.write_string(row, 2, item['release'])
      ws.write_string(row, 3, item['count'])
      ws.write_string(row, 4, item['raiting'])
      ws.write_string(row, 5, item['url'])
