get list of all variables in project

Is there a way to expor all variables in a project, in a .story file, to a text file?

I'd like to use javascript to set a lot of variables at the same time, which I can do, but it would be nice if I did not have to type them all in manually. If I could generate a list of all variables in the project I could copy and paste making sure I don't type any incorrectly and prevent mistakes.

Thanks
