Dump data seamlessly into a Mongodb collection from your browser using a Chrome Extension.
Create a MongoDB Atlas Cluster, attach a Stitch application, and go through the 'Getting Started' page on the Stitch App landing page to create a Stitch app name, db, and collection.
In config.json add your Stitch app name, db, and collection.
Now add this chrome extension by navigating to chrome://extensions. Turn on 'Developer Mode' (top right). Click 'Load Unpacked' and select the folder on your computer this repo is cloned in. Now your chrome extension will be showing in your Chrome Browser.
A good place to search for datasets to insert into your MongoDB collection is Google Dataset Search.
For example, here is a dataset of NYC construction loans: https://data.cityofnewyork.us/resource/dh27-cvaj.json
Highlight the data in this page, click the newly created chrome extension, and click the Insert button.
