Add 'Upload File From Computer' Option
For the Online Excel, it would be nice to be able to upload a file to cloud storage and cloud editing, from a computer that doesn't have OneDrive capabilities (Windows 7 and older). This would be especially useful in situations where you have to work on a file on a non-personal computer, from a flash drive. If the file could be opened in Excel Online and then saved to OneDrive through Excel Online that would be great.
@Anonymous - you can upload a file from a thumbdrive (or wherever) to your OneDrive, and then open it in Excel Online. I think this is basically what you're asking for, except that you start in OneDrive rather than Excel Online. To do this:
1. Connect your flash drive
2. Open a web browser and go to OneDrive.com
3. Log in with your user/pass (the same ones you use for Excel Online)
4. Find the folder where you want to upload your file, and then click Upload.
5. Once the file has uploaded, click on the filename to open it with Excel Online.
Hope that helps - let me know,
