When & Why to Use This Skill
This Claude skill is a comprehensive PDF processing toolkit designed for programmatic document manipulation and data extraction. It empowers users to extract text and structured tables, merge or split PDF files, rotate pages, and generate new documents from scratch using industry-standard Python libraries like pypdf, pdfplumber, and reportlab.
Use Cases
- Automated Data Extraction: Extracting structured text and complex tables from financial reports, invoices, or academic papers for data analysis.
- Document Management & Assembly: Merging multiple PDF reports into a single file or splitting large documents into individual pages for easier distribution.
- Programmatic PDF Generation: Creating dynamic, custom PDF documents such as automated invoices, certificates, or personalized business reports.
- Document Correction & Formatting: Rotating misaligned pages, handling PDF forms, and modifying document metadata programmatically.

常用操作
合并 PDF
from pypdf import PdfWriter, PdfReader
writer = PdfWriter()
for pdf_file in ["doc1.pdf", "doc2.pdf"]:
reader = PdfReader(pdf_file)
for page in reader.pages:
writer.add_page(page)
with open("merged.pdf", "wb") as output:
writer.write(output)
拆分 PDF
reader = PdfReader("input.pdf")
for i, page in enumerate(reader.pages):
writer = PdfWriter()
writer.add_page(page)
with open(f"page_{i+1}.pdf", "wb") as output:
writer.write(output)
提取表格
import pdfplumber
with pdfplumber.open("document.pdf") as pdf:
for page in pdf.pages:
tables = page.extract_tables()
for table in tables:
for row in table:
print(row)
创建 PDF
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
c = canvas.Canvas("new.pdf", pagesize=letter)
c.drawString(100, 750, "Hello World!")
c.save()
旋转页面
reader = PdfReader("input.pdf")
writer = PdfWriter()
page = reader.pages[0]
page.rotate(90) #顺时针旋转 90 度
writer.add_page(page)
with open("rotated.pdf", "wb") as output:
writer.write(output)
命令行工具
# 提取文本 (poppler-utils)
pdftotext input.pdf output.txt
pdftotext -layout input.pdf output.txt # 保留布局
# 合并 PDF (qpdf)
qpdf --empty --pages file1.pdf file2.pdf -- merged.pdf
# 拆分页面
qpdf input.pdf --pages .1-5 -- pages1-5.pdf
