Openpyxl生成的工作簿被外部解析器拒绝,除非在Excel中打开并重新保存(不进行任何更改)

我正在使用Amazon的product-listing-creation模板在Amazon上创建和更新产品列表。 Amazon的模板包括用于将CSV内容导入模板的Excel宏,但我希望绕过此步骤并直接克隆,编辑和重新保存Excel文件。

我有openpyxl代码,用于打开模板,填写单元格并保存带有已填充信息的新副本。为了允许openpyxl读取文件,我必须编辑Amazon提供的模板。我已将每张工作表从原始.xlsm模板复制到空白工作簿中,并将其另存为.xlsx。除了我将在一分钟内详细介绍的错误之外,该文件仍然可以由Amazon处理,因此我不认为应该(完全)责怪格式更改。

这是写输出文件的代码:

def create_workbook(chunk, file_count):
    '''This creates a single output workbook from a chunk of campaign_dicts.'''
    workbook = openpyxl.load_workbook(AMAZON_TEMPLATE_FILENAME)
    sheet = workbook["Template"]

    rows = []
    for campaign_dict in chunk:
        rows += create_rows(campaign_dict) # Returns a list of lists of cell values.

    write_rows_to_sheet(sheet, rows, TEMPLATE_DATA_STARTING_ROW, TEMPLATE_DATA_STARTING_COL)
    workbook.save("output/output" + str(file_count) + ".xlsx")

def write_rows_to_sheet(sheet, rows, starting_row, starting_col):
    '''This writes data to a worksheet of an openpyxl workbook, starting from the given coordinates.
    The rows for this function should be a list of lists, where each list is a row.'''
    for row_number, row in enumerate(rows):
        for column_number, cell in enumerate(row):
            if isinstance(cell, str):
                cell = re.sub(ILLEGAL_CHARACTERS_RE, '', cell)
            sheet.cell(row = row_number + starting_row + 1, column = column_number + starting_col + 1).value = cell
    return sheet  

问题是,当我尝试将此代码生成的任何文件上传到Amazon进行处理时,它会被以下处理报告拒绝:

Feed Processing Summary:
  Number of records processed       0

我发现一种解决方法是在Excel中打开输出文件并立即保存它,而无需对该文件或其数据进行任何更改。我无法发布实际的文件之前和之后(专有信息),但是我知道文件在重新保存之前和之后肯定会发生更改,尽管在保存文件时我没有进行任何更改。这只是开-关-关。请注意,当我打开并重新保存文件时,Excel不会抱怨文件的内容。

是什么原因导致这种情况发生,以及如何在代码中对其进行修复,以使我没有此中间步骤?
