Send/receive data to other programs (like Excel)?

I was reading this definition in Python and got me thinking…

Where can I push/import data from external programs, just like excel?
Is there a way to find the classes and commands of the available programs accesible from the revit api or other methods?



you can more or less do whatever you want… if you know how to code in Python and/or Csharp

the revit api -->
