wps-batch-convert

批量格式转换工具

一个文件夹 → 全部转换 → 输出到目标文件夹。

When to Use

• 批量将Word转PDF
• Excel批量导出CSV
• Markdown转Word
• 整个文件夹的格式转换
• 用户说"批量转PDF""全部导出为CSV"

When NOT to Use

• PDF内容提取 → 使用 wps-pdf-extract
• PDF合并拆分 → 使用 wps-pdf-merge-split

支持的转换路径

源格式	目标格式	工具
.docx	.pdf	python-docx + reportlab 或 WPS CLI
.docx	.txt	python-docx
.xlsx	.csv	openpyxl
.csv	.xlsx	openpyxl
.pptx	.pdf	python-pptx + WPS CLI
.md	.docx	markdown + python-docx
.txt	.docx	python-docx

工作流程

Step 1: 确认转换需求

• 源格式和目标格式
• 文件列表或文件夹路径
• 输出位置

Step 2: 批量转换
