I am using win32.client in python for converting my .xlsx and .xls file into a .csv. When I execute this code it's giving an error. My code is:

推荐答案

我会使用 xlrd - 它更快、跨平台并且直接处理文件.需要注意的一件事 - 它不适用于 xlsx 文件 - 因此您必须将 Excel 文件另存为 xls. 从 0.8.0 版开始，xlrd 读取 XLS 和 XLSX 文件.

I would use xlrd - it's faster, cross platform and works directly with the file. One thing to note - it doesn't work on xlsx files - so you'd have to save your Excel file as xls. As of version 0.8.0, xlrd reads both XLS and XLSX files.

import xlrd
import csv

def csv_from_excel():
    wb = xlrd.open_workbook('your_workbook.xls')
    sh = wb.sheet_by_name('Sheet1')
    your_csv_file = open('your_csv_file.csv', 'wb')
    wr = csv.writer(your_csv_file, quoting=csv.QUOTE_ALL)

    for rownum in xrange(sh.nrows):
        wr.writerow(sh.row_values(rownum))

    your_csv_file.close()
