7. 选择 ConvertToBeamer → 点击执行

第四步：获取输出文件

• 生成的 .txt 文件会保存在 .ppt 文件所在的同一文件夹 中
• 可直接将文件内容复制到你的 LaTeX Beamer 文档正文中使用

输出代码示例

\section{PresentationName}\begin{frame}\frametitle{幻灯片标题}幻灯片正文内容\end{frame}

限制说明

• 仅提取文本和基础形状，不保留复杂格式
• 表格、图表、动画、切换效果无法转换

PPT to LaTeX Beamer Converter VBA Script

Overview

This VBA macro extracts text and basic content from Microsoft PowerPoint (.ppt) presentations and converts them into a LaTeX Beamer frame structure, saving the output as a text file for direct use in Beamer presentations.
