1 xlsx檔案轉csv檔案

import xlrdimport 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()

2 使用第三方庫pandas將xlsx檔案轉csv檔案

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()

3 csv檔案轉換成xlsx檔案

import csvimport 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‘)  # 建立一個sheet表格        l = 0        for line in read:            print(line)            r = 0            for i in line:                print(i)                sheet.write(l, r, i)  # 一個一個將儲存格資料寫入                r = r + 1            l = l + 1         workbook.save(‘1.xlsx‘)  # 儲存Excel   if __name__ == ‘__main__‘:    csv_to_xlsx()

4 使用pandas將csv檔案轉成xlsx檔案

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()
