Somethings like CouchDB are a database that store it internally in a file. Most people don't /store/ JSON at all, they generate it and send it, or parse it and process it.

JSON is an ideal format for serializing data, but the same caveats apply to it as any other serialization format. Do you store XML in a DB? Usually not. The difference being XML makes sacrifices to include humans use, and JSON makes sacrifices to be easily parseable and fast.

JSON is not really a replacement for a CSV. Think of a CSV as loosely-formated table specific dumping mechanism. It wouldn't make too much sense to have a JSON export in excel.
