Read an xlsx file from a NAS (smbConnection)

Question

I'm trying to read an xlsx file stored in a NAS, using smb.SMBConnection. I did this :

from smb.SMBConnection import SMBConnection
import tempfile

conn = SMBConnection('username', 'password', 'name', 'name')
conn.connect('10.111.111.111')
results = conn.listPath('shared_folder_name', 'path')
for x in results:
    print(x.filename)

And I read successfully the files of the folder. But I wand to import one of them on a pandas dataframe. How can I do that ?

I created a tempory file but failed to read it.

file_obj = tempfile.NamedTemporaryFile()
file_name = file_obj.name
file_attributes, copysize = conn.retrieveFile('data', "path/data.xlsx", file_obj)

Thanks in advance.
