Avg Bid (USD)
Project Budget (USD)
$30 - $40

Project Description:
I need to extract some data from a private Google Spreadsheet, from Python AppEngine or directly from an HTML page.
I found plenty of partial examples but not a working mock up of this functionality dealing with oAuth 2.0.
What I want is a working example which can be deployed showing me the content of the first sheet of a worksheet
The mock up must receive as a parameter the worksheet key and fully exploit tha Google Authentication

I could consider to kind of solutions :
1. a solution implemented as a GAE Python mockup in this case the mockupo would receive the needed parameters as GETparameters
2. a web page exploiting the last version of the Google javascript API for this objective

What I want:

The full source code of the solution
A clear explanation of the deployment ( considering the API configuration and how these values must be configured in the mock up)
A testable deployment

I really want to deploy, give the sheet key and see my data

No fancy graphics or similar, just the print of the sheet in table form or json or xml

Please reply to this offer with the initials of "Google App Engine Javascript" as a first row
