Google Refine Uploader and Stats Extension



The Google Refine Uploader Extension allows you to export datasets from Google Refine and post them as JSON to web servers! Intended for use with CouchDB. Please note that this extension is a work in progress. Feel free to join and help 


This extension is based on Chicago Tribune Stats extension. A tutorial is available on their blog. Please note that the extension does not work with Google Refine 2.5. It should be tested with the 2.0 version available here.

If you have installed and tried any of those two extensions, I`ll be pleased to heard from you!
