Once you've set up the outline you can change the size, color, and font of your text, which will convert to PowerPoint.

TL;DR in Chinese:
使用Microsoft Word打开文档。 用标题分隔每个“幻灯片”。 跳转到“样式”菜单。 将标题高亮，然后单击“标题1”。 将幻灯片内容格式化为“标题2”。 使用“标题3”添加子项目符号。 用空格隔开每张幻灯片。 也可以自定义文字。 使用“文档” →“发送到PowerPoint”将文档发送到PowerPoint。 在PowerPoint中自定义演示文稿。
