python3读取xlsx文件内容

相关模块：
- openpyxl
- xlsxwriter
- xlrd只读取xls文件中的内容

openpyxl:
(部分内容来自官网http://openpyxl.readthedocs.io/en/stable/usage.html)
阅读现有的工作薄：
from openpyxl import load_workbook
wb = load_workbook(filename="文件名")
sheet_ranges = wb["sheet名"]
print(sheet_ranges['D18'].value) # 将index为D18的值读取出来

 

xlwt例子：

import xlwt, os, sys, glob, time, datetime

# define parameter
filepath = 'infomations.txt'
xlsname = '20230410.xls'

# class instance
workbook = xlwt.Workbook(encoding='ascii')
worksheet = workbook.add_sheet('第一个page')
style = xlwt.XFStyle()  # 初始化样式

# define style
font = xlwt.Font()  # 创建字体
font.name = '微软雅黑'
font.bold = True  # 黑体
font.underline = False  # 下划线
font.italic = True  # 斜体
style.font = font  # 设定字体

# 设置对齐方式
alignment = xlwt.Alignment()  # 创建对齐方式
alignment.horz = 0x02
alignment.vert = 0x01
alignment.wrap = 0x01
style.alignment = alignment

 

xlswriter例子：

import xlsxwriter

"""
    只能写入xlsx文件内容，不能读取
    每次都是一个全新的sheet
"""

xlsname = 'hello.xlsx'


workbook = xlsxwriter.Workbook(xlsname)
worksheet1 = workbook.add_worksheet('第一个sheet页')
bold = workbook.add_format({'bold': True})
worksheet1.write(0,1, 'hello world', bold)

worksheet2 = workbook.add_worksheet('第二个sheet页')
worksheet2.write(0,1, 'hello world', bold)
workbook.close()

xlrd例子：

import xlrd
# xlrd仅支持xls格式的excel文档读取,这个读取比较简单，不做详细的笔记
xlsname = '20230410.xls'
xlsname2 = 'V20230407-01.xlsx'


exec = xlrd.open_workbook(xlsname)

sheet1 = exec.sheet_by_index(0)


num_rows = sheet1.cell(1,0).value

print(num_rows)
