对这些 .xls 文件的格式感到非常困惑，因为它们并不是真正的 .xls 文件，我将文件的前几行放在下面以供参考，完整文件在这里。

转换正常的 .xls 是没有问题的p.save_book_as(file_name=fname, dest_file_name=fname+'x')。

我想用python批量转换为.xlsx，这甚至可以用以下格式吗？

这似乎是“与 Excel 兼容的 HTML ”。虽然我不知道纯 python 转换器，但您可以尝试使用 excel 作为外部转换器，即打开这些文件并将它们保存到 xlsx，如下所述并复制如下。这需要 pywin32 包，才能远程访问 excel。

import win32com.client as win32
fname = "full+path+to+xls_file"
excel = win32.gencache.EnsureDispatch('Excel.Application')
wb = excel.Workbooks.Open(fname)

wb.SaveAs(fname+"x", FileFormat = 51)    #FileFormat = 51 is for .xlsx extension
wb.Close()                               #FileFormat = 56 is for .xls extension
excel.Application.Quit()
