Launch batch script after Dynamo script

Hello,

I have written a dynamo script which exports schedule data to an Excel file.
This is working great but I still have to find how to close the file opened by the node Write To Excel.

After that I need to run a python script which will parse data and calculate sums and so on.
Unfortunately this can’t be done inside Dynamo as my script need more libs than what is included in IronPython.

So is it possible to launch a batch script or an external python script from Dynamo or Revit?
OR Is it possible to launch a Dynamo script from a batch file?
The two ways are good for me?

Thanks.

Hi Clement

Have a look here, you might be able to use the libs through an intermediate file as described by @Dimitar_Venkov here:
