前言
Python中常用的操作Excel的三方包有xlrd,xlwt和openpyxl等,xlrd支持读取.xls和.xlsx格式的Excel文件,只支持读取,不支持写入。xlwt只支持写入.xls格式的文件,不支持读取。
openpyxl不支持.xls格式,但是支持.xlsx格式的读取写入,并且支持写入公式等。
原始数据文件apis.xlsx内容:
name | method | url | data | json | result |
---|---|---|---|---|---|
get接口 | get | https://httpbin.org/get?a=1&b=2 | |||
post表单接口 | post | https://httpbin.org/post | {name: Kevin,age:1} | ||
post-json接口 | post | https://httpbin.org/post | {name: Kevin,age: 21} |

import openpyxl
# 打开excel
excel = openpyxl.load_workbook( 'apis.xlsx' ) # 有路径应带上路径
# 使用指定工作表
sheet = excel.active # 当前激活的工作表
# sheet = excel.get_sheet_by_name('Sheet1')
# 读取所有数据
print ( list (sheet.values)) # sheet.values 生成器
print (sheet.max_column) # 最大列数
print (sheet.max_row) # 最大行数

显示结果:
[('name', 'method', 'url', 'headers', 'data', 'json', 'result'), ('get接口', 'get', 'https://httpbin.org/get?a=1&b=2', None, None, None, None), ('post表单接口', 'post', 'https://httpbin.org/post', 'cookie: token=123', '{name: Kevin,age: 21}', None, None), ('post-json接口', 'post', 'https://httpbin.org/post', None, None, '{name: Kevin,age: 21}', None)]
