Access data in Excel – Reuter from python

Access data in Excel – Reuter from python

I’m using Reuters integrated in Excel to retrieve market data. For task automation , I currently use VBA but now I want to switch to python. The package pyxll does not help much because the principle is the same as VBA (I need to be inside Excel and click on the RUN button…)
So I’m considering using win32com to access to Excel from outside with COM object. However, when I do:

from win32com.client import Dispatch 
xlApp = Dispatch("Excel.Application")

This code opens a new instance of Excel that does not have Reuter add-in in there (thus I can’t use the Reuter function to retrieve data). I don’t know how to access to Excel-with-Reuter instance from python?
I’ve taken a look at Com Explorer to explore the service and I didn’t see any other service than Excel

Try this –

import os
from win32com.client import GetObject

os.startfile(r'C:pathtoReutersExcel.exe')
xlApp = GetObject(None, 'Excel.Application')

If you’re using Excel to access Thomson Reuters Dataworks Enterprise (former Datastream), then have a look on pydatastream (https://github.com/vfilimonov/pydatastream) – it’ll allow you to get the data directly to python in pandas.DataFrame format.
