Why is it not being written to *.xlsx file in Python?

Question

Python

Hello, I don’t know why, but my data does not want to be saved in an excel file ((

wb = load_workbook('output/output.xlsx')

def write_fields_to_excel(name):
    if name not in wb.sheetnames:
        ws = wb.create_sheet(name)
        for k in sorted(fields):
            ws[k] = fields[k]
        wb.save('output/output.xlsx')

def write_to_excel(data, pos, name):
    ws = wb[name]
    ws['A' + pos] = pos - 1
    ws['B' + pos] = data.get('Полное наименование/ФИО ИП', '')
    ws['C' + pos] = data.get('Адрес места нахождения ЮЛ/ИнЮЛ или жительства ИП', '')
    ws['D' + pos] = data.get('ОГРН', '')
    ws['E' + pos] = data.get('В лице', '')
    ws['F' + pos] = data.get('ФИО руководителя', '')
    ws['G' + pos] = data.get('Номер телефона', '')
    ws['H' + pos] = data.get('Адрес электронной почты', '')
    ws['I' + pos] = data.get('Регистрационный номер', '')
    ws['J' + pos] = data.get('Дата начала действия', '')
    ws['K' + pos] = data.get('Дата окончания действия', '')
    ws['L' + pos] = data.get('Схема декларирования', '')
    ws['M' + pos] = data.get('Статус', '')
    ws['N' + pos] = data.get('Стандарты', '')
    ws['O' + pos] = data.get('ТН ВЭД', '') if data.get('ТН ВЭД', '') else data.get('ТН ВЭД ТС', '')
    wb.save('output/output1.xlsx')
    print('done')

The data variable has all the data, but "print('done')" is not displayed!

write_fields_to_excel(name)
...
data[key] = value
write_to_excel(data, pos, name)
...
