使用Google电子表格作为应用的数据库

I want to use Google spreadsheets to store data online so multiple people can enter and maintain data, then publish or export (csv, xls, ods) the sheet for their application. What is the easiest way to process the sheet? If the data can be accessed as a link the updates could be immediately reflected in the client's app.I want to use Google spreadsheets to store data
