是否可以在 Python 中将下面奇怪的 .XLS 文件(实际上是某种 HTML/XML 格式)转换为 .XLSX?

Is it possible in Python to convert the below strange .XLS file, which is actually in some HTML/XML format to .XLSX?

对这些.xls文件的格式感到很困惑,因为它们不是真正的.xls文件,我把文件的前几行放在下面供参考,full file here

使用 p.save_book_as(file_name=fname, dest_file_name=fname+'x') 转换普通 .xls 没有问题。

我想使用 python 批量转换为 .xlsx,是否可以使用以下格式?

这似乎是“Excel compatible 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 described here 并复制到下面。这需要 pywin32 包,以远程访问 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()
