用python将Excel的xlsx格式批量转换为txt格式，直接上代码：

# 加载相应的package
import pandas as pd
import openpyxl
import os

# 输入路径
inpath = "D:/Desktep/xlsx"
# 输出路径
outpath = "D:/Desktep/txt"

# 读取excel文件
for afile in os.listdir(inpath):
    if afile[-4:].lower() == 'xlsx':
        print(afile)
        name = inpath + '/' + afile
        # 读取每一个sheet
        wb = openpyxl.load_workbook(name)
        sheets = wb.sheetnames
        for sheet in sheets:
            print(sheet)
            df = pd.read_excel(name, sheet_name=sheet, header=None)
            print('开始写入txt文件...')
            # 保存txt文件
            df.to_csv(outpath + '/' + afile[:-5] + '_' + sheet + '.txt', header=None, sep=',', index=False)
            print('文件写入成功!')
