Probably a good idea. :)
Meanwhile, here is a screenshot from one of my projects. It loads array of data from a simple text file(json format):
<img src="https://dl.dropboxusercontent.com/u/19921470/ajax.PNG" border="0" />
Here are contents of the text file:
{
"c2array":true,
"size":[5,7,1],
"data":[
[["Bob the Builder"],["He builds things."],[1],[2],[10],[100]],
[
["Ben the Builder"],["He builds things."],[1],[2],[10],[100]],
[
["Bill the Builder"],["He builds things."],[1],[2],[10],[100]]
