Looking for text editor with multiple functionalities : <p>I'm building a web app; front-end in Angular and back-end in Ruby on Rails.</p>

<p>I need to achieve below functionalities. I am basically adding text editor so users can edit template letters in my service.</p>

<pre><code>1) Load .doc file from the file system(or remote server) to the text editor
2) Edit the loaded .doc file and save the file as different name
</code></pre>

<p>Is there any recommendable free text editor which can achieve those?</p>
