Python之xlsx文件与csv文件相互转换  
在Python中，可以使用xlrd和csv模块来处理Excel文件和csv文件。

xlsx文件转csv文件

import xlrd
    import csv
    
    def xlsx_to_csv():
        workbook = xlrd.open_workbook('1.xlsx')
        table = workbook.sheet_by_index(0)
        with codecs.open('1.csv', 'w', encoding='utf-8') as f:
            write = csv.writer(f)
            for row_num in range(table.nrows):
                row_value = table.row_values(row_num)
                write.writerow(row_value)
    
    if __name__ == '__main__':
        xlsx_to_csv()

在2个文件之间转换，需要注意一个文件的字符转码问题。

使用第三方库pandas将xlsx文件转csv文件

import pandas as pd
    
    def xlsx_to_csv_pd():
        data_xls = pd.read_excel('1.xlsx', index_col=0)
        data_xls.to_csv('1.csv', encoding='utf-8')
    
    if __name__ == '__main__':
        xlsx_to_csv_pd()

csv文件转换成xlsx文件

import csv
    import xlwt
    
    def csv_to_xlsx():
        with open('1.csv', 'r', encoding='utf-8') as f:
            read = csv.reader(f)
            workbook = xlwt.Workbook()
            sheet = workbook.add_sheet('data')  # 创建一个sheet表格
            l = 0
            for line in read:
                print(line)
                r = 0
                for i in line:
                    print(i)
                    sheet.write(l, r, i)  # 一个一个将单元格数据写入
                    r = r + 1
                l = l + 1
             workbook.save('1.xlsx')  # 保存Excel
             
    if __name__ == '__main__':
        csv_to_xlsx()

使用pandas将csv文件转成xlsx文件

import pandas as pd
    
    def csv_to_xlsx_pd():
        csv = pd.read_csv('1.csv', encoding='utf-8')
        csv.to_excel('1.xlsx', sheet_name='data')
    
    if __name__ == '__main__':
        csv_to_xlsx_pd()
