从入门到实战详解Python实现办公自动化的最全指南

# 办公自动化必备库
pip install pandas openpyxl python-docx python-pptx pypdf2 python-dotenv smtplib

import pandas as pd

# 1. 读取Excel文件
df = pd.read_excel("数据.xlsx", sheet_name="Sheet1")

# 2. 筛选数据（例：筛选销售额>5000的记录）
result = df[df["销售额"] > 5000]

# 3. 批量写入新Excel
result.to_excel("筛选结果.xlsx", index=False)

# 4. 批量合并多个Excel文件
file_list = ["文件1.xlsx", "文件2.xlsx", "文件3.xlsx"]
combined = pd.concat([pd.read_excel(f) for f in file_list])
combined.to_excel("合并总表.xlsx", index=False)

from docx import Document

# 1. 新建Word文档
doc = Document()

# 2. 添加标题、段落
doc.add_heading("自动化生成的报告", 0)
doc.add_paragraph("这是Python自动生成的正文内容")

# 3. 批量替换文字（模板改合同神器）
for paragraph in doc.paragraphs:
    if "[姓名]" in paragraph.text:
        paragraph.text = paragraph.text.replace("[姓名]", "张三")

# 4. 保存文档
doc.save("生成文档.docx")

# 3. 自动发送邮件
