They do not *need* JSON, these parsers *create* JSON, because JSON *is*
the format to store data for JavaScript.

JSON = JavaScript Object Notation

And don't get confused by "Object" - JSON just represent serialized data
which is called "objects" since the data can be accessed using property
names.

No, you just download the stuff, integrate it in your own code and
that's it. There is no need for a server.

Did you ever use a JavaScript library from others? It seems you don't
have any experience at all with this.
