在 Python 3 中将 XLS 文件转换为 XLSX？

Question

My objective is to take a large number of XLS files and convert them to XLSX. I can do it one line at a time with a simple operation, or do a large number of files in a batch if anyone knows a way.

I attempted to use most of the solutions on this Stack post , but it seems they no longer work, or apply. It is 9 years old, so a modern solution may be needed.

Code I tried:

p.save_book_as(file_name='C://Users//user1//Downloads//oldfile.xls',
           dest_file_name='C://Users//user1//Downloads//oldfile.xlsx')

But this resulted in an error:

 raise XLRDError('Unsupported format, or corrupt file: ' + msg)
xlrd.biffh.XLRDError: Unsupported format, or corrupt file: Expected BOF record; found b'<?xml ve'

Answer 1

You could try Tablib , as in:

with open('input.xls', 'r') as input:
    data = Dataset().load(input)
    with open('output.xlsx', 'wb') as output:
        output.write(data.export('xlsx'))

Not sure if it supports your versions of xls/xlsx, though.
