Overview

This collection of files serves as a simple static demonstration of how to post to a google spreadsheet from an external html <form> following the example by Martin Hawksey

Run example

You should be able to just open index.html in your browser and test locally.

However if there are some permissions errors you can make a quick html server with python. Open terminal and cd to the directory where the gist files are located and enter python -m SimpleHTTPServer. By default this creates a local server at localhost:8000
