Hi,
I'm trying to open a xslx in excel using the url scheme the US shown here https://msdn.microsoft.com/en-us/library/office/dn906146.aspx, but it isn't working.

My code:
```
from objc_util import nsurl,UIApplication

excel_file = 'David Jorge - 2017-08 Agosto.xlsx'
url='ms-excel:ofv|u|{}'.format(excel_file)

print(url)
app = UIApplication.sharedApplication()
app.openURL_(nsurl(url))
```

Can anyone help me with this?
