前言：
本文基于html5技术，以及微软接口，实现html5在线预览PPT、Excel、Word、Pdf。
在线预览PPT
代码：
<iframesrc='https://view.officeapps.live.com/op/embed.aspx?src=pptx线上地址'width='1000px' height='800px' frameborder='1'></iframe>留神：此办法，不止后缀为.ppt格局的文件，只反对.pptx文件，如果ppt文件不多，能够关上Wps或者Office将其手动转换，如果过于多，能够应用上面办法，基于Python批量将PPT转换为pptx：请点击 ppt批量转换pptx
在线预览Excel
<iframesrc='https://view.officeapps.live.com/op/embed.aspx?src=xlsx线上地址'width='1000px' height='800px' frameborder='1'></iframe>在线预览Word
<iframe src="https://view.officeapps.live.com/op/view.aspx?src=docx线上地址" width='1000px' height='800px' frameborder='1'></iframe>在线预览Pdf
步骤：
1、首先援用pdfOnLine.js

<body> <p id="example1"></p></body>3、script加载pdf
<script> var options = { height: "550px", pdfOpenParams: {view: 'FitV', page: '0' }, name:"mans", fallbackLink: "<p>您的浏览器暂不反对此pdf，请下载最新的浏览器</p>" }; PDFObject.embed("pdf/test.pdf", "#example1",options);</script>
