Python3利用openpyxl读写Excel文件的方法实例
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} |
读取数据
读取所有数据
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)]

按行读取
代码接上例
... # 按行读取 for row in sheet.iter_rows(min_row=1, min_col=1, max_col=3, max_row=3): print(row) # 读取标题行 for row in sheet.iter_rows(max_row=1): title_row = [cell.value for cell in row] print(title_row) # 读取标题行以外数据 for row in sheet.iter_rows(min_row=2): row_data = [cell.value for cell in row] print(row_data)
打印结果:
(<Cell 'Sheet1'.A1>, <Cell 'Sheet1'.B1>, <Cell 'Sheet1'.C1>)
(<Cell 'Sheet1'.A2>, <Cell 'Sheet1'.B2>, <Cell 'Sheet1'.C2>)
(<Cell 'Sheet1'.A3>, <Cell 'Sheet1'.B3>, <Cell 'Sheet1'.C3>)
['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]
读取单元格数据
代码接上例
... # 读取单元格数据 print(sheet['A1'].value) print(sheet.cell(1,1).value) # 索引从1开始
打印结果:
name
name
写入文件
代码接上例
# 写入单元格 sheet['F2'] = 'PASS' result_col = title_row.index('result')+1 # 'result'所在的列号 sheet.cell(3, result_col).value = 'PASS' # 整行写入 new_row = ['post-xml接口', 'post', 'https://httpbin.org/post'] sheet.append(new_row) # 保存文件,也可覆盖原文件 excel.save("apis2.xlsx")
写入结果:
name | method | url | data | json | result |
---|---|---|---|---|---|
get接口 | get | https://httpbin.org/get?a=1&b=2 | PASS | ||
post表单接口 | post | https://httpbin.org/post | {name: Kevin,age:1} | PASS | |
post-json接口 | post | https://httpbin.org/post | {name: Kevin,age: 21} | ||
post-xml接口 | post | https://httpbin.org/post |
