SIMILI is a project of MIT where they have been developing various API’s.
Exhibit is one of the API which we use to display complex data and is maintained by Google labs now. Exhibit is a three-tier web application framework written in Javascript, Few hundred records of data we have is shown by just creating a data file and a simple html file which describes how the data should be displayed..Data file is in JSON format and we have converted all the data in access database to JSON format by making some modifications with the existing database.
Basic idea of Exhibit can be found here
They provide a tool to convert the data from excel to JSON and it can be done by using babel
If you have a huge data and not sure how to organize them, Exhibit would do wonders with those data.
