title: What is the best way to edit google docs using the API?
body: <p>I'd like to be able to edit any kind of Google docs using the API from Google App Engine.
  My goal is to lose as little information as possible when editing the document. The edits are fairly simple like replacing some words.</p>
  
  <ul>
  <li>Document</li>
  </ul>
  
  <p>To edit them, I'm doing an export in HTML and importing it again. But we are loosing some information like notes. There is also an issue with the title, the size before each title increase at every new update, so I have to reset some css. Is there is a better way of editing docs ?</p>
  
  <ul>
  <li>Spreadsheet</li>
  </ul>
  
  <p>There is the spreadsheet API, so I think I'm covered.</p>
  
  <ul>
  <li>Presentation</li>
  </ul>
  
  <p>I did not find a format that I could export and import again. The only one seems to be powerpoint. But powerpoint files cannot be easily edited.</p>
  
  <ul>
  <li>Drawing</li>
  </ul>
  
  <p>I did not find a format that can be both exported and imported. I tried with SVG, but svg cannot be imported back.</p>
