title: How do I import JSON files to firebase without importing manually
body: <p>Currently, to import bulk data to firebase, we have to go to our firebase console browse for json file and import it in. <a href="http://i.stack.imgur.com/L8uCr.png" rel="nofollow">e.g. of import button</a></p>
  
  <p>However, I want to import it without going in to the console. 
  That is, my system (web app) will allow admin to override all data in database with a default JSON file.</p>
  
  <p>I don't think the Firebase API (<a href="https://www.firebase.com/docs/web/guide/saving-data.html" rel="nofollow">https://www.firebase.com/docs/web/guide/saving-data.html</a>) provide such feature. Any recommendations?</p>
