Embed Spire.Cloud.Office in Your Web Application

Spire.Cloud.Office is a JavaScript document editor which you can use to create, edit, convert, print, view and save MS Word and Excel documents in a browser on Windows, Linux and Mac. This article demonstrates how to incorporate Spire.Cloud.Office online editor (JavaScript) into a HTML document, so you can run the editor directly in your web application or cloud application.

Step 1. Install Spire.Cloud.Office

Before you can embed the document editor in your HTML file, you’ll need to install Spire.Cloud.Office on your system.

After installation, you can visit our sample file management system and editor on port 3000, and connect to our service via port 8000. In this tutorial, Spire.Cloud.Office is installed on our local server

Step 2. Embed Editor in Your HTML Document

Below is a sample HTML in which our document editor is embedded. You can download it and modify some key parameters in it to run our editor in a HTML page.
