Best alternative i think is uploading file in GD page.
Try this (tested):
1. 'Display select file dialog' to choose Excel file (File filter = *.xlsx). Output var: %SelectedFile%
2. Launch your preferred browser (Initial URL = https://www.google.com/drive/)
3. 'Click UI element in window' and click in Access Drive' button
4. Use 'Populate text field in window' and ''Click UI element in window' to proceed with login and password (if necessary)
Once in the Google Drive main page:
5. 'Press button in window'. Capture 'My Drive' button (button[Name="My Drive"])
6. 'Select menu option in window'. Capture 'Upload files' option (menuitem[Name="Upload files"])
This will open a window to select file. In this window:
7. 'Click UI element in window' and capture 'Name' field (edit[Name="Name")
8. 'Populate text field in window'. Text box: Name field, Text = %SelectedFile%
9. 'Press button in window' and capture Open button (button[Name="Open"])
Or, if you have a GD folder in your computer, save the file in this folder and launch GD app to synchronize it.
