We're trying to send Aspose.Cells output directly to Google Docs accounts. XLS output works fine, identical XLSX doesn't. Google rejects the XLSX with a "cannot convert" error and no additional information. If I open the XLSX in Excel, resave it, then send it to Google Docs it works fine. We'd prefer to use XLSX since its compressed format will let us upload larger files. Do you have any experience with Aspose output and Google Docs?
Thanks,
