sheetrock.js – is a jQuery plugin for querying, retrieving, and displaying data from Google Spreadsheets. Use it to load entire sheets or leverage SQL-like queries to treat Google Spreadsheets as a quick-and-dirty JSON datastore. All you need is the URL of a public Google Spreadsheet. It requires no backend code whatsoever—everything is done in the browser.
Google Doc has many neat hidden feature you might not know about, for instance, you can use Google Doc to monitor website up time, use Google doc to do large file conversion and recovery. Recently, I discovered you can use Google Doc’s spreadsheet to serve JSON static data. This means, for some simple web application that needs server to serve some form of static data will no longer require you as a developer to write any server component code. It also provided a very user friendly medium for you to update the data inside Google doc. If you know the ramification of this, you’d appreciate the shortcut.
