pdf-ppt-docx-xlsx-tools

文档格式转换工具集，支持 PDF、PPTX、DOCX、XLSX 四种格式之间的互转及衍生操作（转图片、合并、拆分、提取文本/表格、加水印等）。当用户需要转换文档格式、处理 PDF、操作 Office 文件时使用此技能。

Install

openclaw skills install @uwvwko-zzz/uwvwko-pdf-ppt-docx-xlsx-tools

PDF / PPTX / DOCX / XLSX 文档转换工具集

四大办公文档格式的转换、提取、合并、拆分工具。基于 Python 生态，所有操作均可通过 execute_command 执行 Python 一行命令或短脚本完成。

依赖安装

bash

pip install PyMuPDF pdf2docx python-docx python-pptx openpyxl pandas Pillow pdfplumber

部分操作（DOCX→PDF、PPTX→PDF、XLSX→PDF）需要系统安装 LibreOffice：

bash

# Windows (winget)
winget install LibreOffice.LibreOffice

# macOS
brew install --cask libreoffice

# Ubuntu/Debian
sudo apt install libreoffice

PDF 转图片如需高质量渲染，可选装 poppler（PyMuPDF 内置渲染已足够，poppler 仅作为备选）。

转换命令详解

1. PDF → 图片

bash

python -c "
import fitz, sys, os
pdf_path, out_dir = sys.argv[1], sys.argv[2] if len(sys.argv)>2 else '.'
os.makedirs(out_dir, exist_ok=True)
doc = fitz.open(pdf_path)
dpi = int(sys.argv[3]) if len(sys.argv)>3 else 200
fmt = sys.argv[4] if len(sys.argv)>4 else 'png'
for i, page in enumerate(doc):
    pix = page.get_pixmap(dpi=dpi)
    out = os.path.join(out_dir, f'page_{i+1:04d}.{fmt}')
    pix.save(out)
    print(f'Saved: {out}')
doc.close()
print(f'Done: {len(doc)} pages -> {out_dir}')
" "input.pdf" "./output_images" 200 png

参数说明：

arg1 — PDF 文件路径
arg2 — 输出目录（默认当前目录）
arg3 — DPI 分辨率（默认 200，推荐 150~300）
arg4 — 图片格式：png（默认）或 jpg

2. PDF → DOCX

bash

python -c "
from pdf2docx import Converter
import sys
cv = Converter(sys.argv[1])
cv.convert(sys.argv[2] if len(sys.argv)>2 else 'output.docx')
cv.close()
print('Done')
" "input.pdf" "output.docx"

可选参数（通过修改脚本）：

start=0, end=None — 指定页码范围
multi_processing=True — 多进程加速大文件

3. PDF → PPTX（每页一张幻灯片）

bash

python -c "
import fitz, sys
from pptx import Presentation
from pptx.util import Inches
from pptx.dml.color import RGBColor
import io

pdf_path = sys.argv[1]
out_path = sys.argv[2] if len(sys.argv)>2 else 'output.pptx'
doc = fitz.open(pdf_path)
prs = Presentation()
prs.slide_width = Inches(13.333)
prs.slide_height = Inches(7.5)

blank_layout = prs.slide_layouts[6]  # blank
for i, page in enumerate(doc):
    pix = page.get_pixmap(dpi=200)
    img_data = pix.tobytes('png')
    slide = prs.slides.add_slide(blank_layout)
    slide.shapes.add_picture(io.BytesIO(img_data), Inches(0), Inches(0),
                             width=prs.slide_width, height=prs.slide_height)
    print(f'Page {i+1}/{len(doc)} added')

prs.save(out_path)
doc.close()
print(f'Done: {out_path}')
" "input.pdf" "output.pptx"

4. PDF → XLSX（提取表格）

bash

python -c "

            for row in table:
                ws.append(row)
            row_offset += len(table)
            print(f'Page {page_num+1}, Table {t_idx+1}: {len(table)} rows')

if ws_total.max_row == 1 and ws_total.max_column == 1:
    wb.remove(ws_total)

wb.save(out_path)
print(f'Done: {out_path}')
" "input.pdf" "output.xlsx"

" "input.xlsx" "filtered.xlsx" 0 "金额 > 1000"

错误处理指南

错误	原因	解决方案
`ModuleNotFoundError`	缺少 Python 依赖	运行 `pip install <包名>`
`FileNotFoundError: soffice`	未安装 LibreOffice	安装 LibreOffice 并确认路径
`pdf2docx` 转换布局错乱	复杂排版 PDF	改用 PDF→图片→PPTX 方案
中文乱码	编码问题	CSV 使用 `utf-8-sig`；确保系统有中文字体
`poppler not found`	pdf2image 需要 poppler	改用 PyMuPDF（`fitz`），不依赖 poppler
大文件内存不足	文件过大	使用逐页处理，避免一次性加载

LibreOffice 路径参考

系统	默认路径
Windows	`C:\Program Files\LibreOffice\program\soffice.exe`
macOS	`/Applications/LibreOffice.app/Contents/MacOS/soffice`
Linux	`/usr/bin/soffice` 或 `/usr/bin/libreoffice`

提示：如果 LibreOffice 不在默认路径，可通过 where soffice（Windows）或 which soffice（Linux/macOS）查找实际路径，替换脚本中的路径即可。

脚本方式（推荐）

除了上面的内联 python -c 命令，所有转换操作也提供了独立脚本，位于 scripts/ 目录。脚本方式更易读、更易调试，适合复杂参数场景。

脚本根目录： workspace/skills/pdf-ppt-docx-xlsx/scripts/

使用原则

优先使用 Python 库方案（PyMuPDF、pdf2docx 等），不依赖 LibreOffice 的转换更快更可控
Office 格式转 PDF 时使用 LibreOffice，保真度远优于纯 Python 方案
大文件分页处理，避免内存溢出
输出路径使用绝对路径或明确的相对路径，避免歧义
转换前检查文件是否存在，转换后验证输出文件大小非零
简单场景用内联命令，复杂场景用 scripts/ 脚本——脚本支持更多参数且更易调试 </task_progress>
