Opening multiple documents in a same window with UNO

Question

I have script in python using pyuno that extracts data from many excel files.

My problem is that for every file I open and close a window with

url = unohelper.systemPathToFileUrl(os.path.abspath(file_name))
file = desktop.loadComponentFromURL(url, "_blank", 0, () )

and

file.close(True)

Is there any way to extract data from the files without opening a window at all? Or at least without opening a new window for each file?
