excel file on icloud drive is disappeared when I edit on my Windows laptop

Hi nowhiz,

Welcome to Apple Support Communities. We understand that you're having an issue with the names of your files in iCloud Drive. We'd like to help.

Just to confirm, this is an issue you're seeing with files that you've created in Excel only. Is that correct? Do you have any updates available for your PC or app? That's always a good first step to check.

Have you been able to successfully upload these in the past? Check out this resource to make sure you're following the steps to add those files: View, add, or remove iCloud Drive files in iCloud for Windows - Apple Support

Add files to iCloud Drive

1. On your Windows computer, open File Explorer or Windows Explorer, then click iCloud Drive in the Navigation pane.

2. Drag files to iCloud Drive.

You can access these files on all your devices that have iCloud Drive turned on. See Set up iCloud Drive on all your devices in the iCloud User Guide.

Note: Some apps, like Pages, Numbers, and Keynote, have their own folders in iCloud Drive. You can only upload a file into an app’s folder if the app can open the file.

Let us know how that goes and we'll continue from here.

Take care!

Hey nowhiz,

Thanks for the update. If it change the original file and created a second file, it may have been updated or in the process of updating if changes were made. This article has some more information on When changes to your files upload to iCloud.

When changes to your files upload to iCloud

The amount of time it takes for your changes to upload to iCloud depends on the app you're using. Pages, Numbers, and Keynote regularly upload files to iCloud so you don’t lose any changes. Other apps upload your files to iCloud only after you save them to the iCloud Drive folder. To see your saved files on a Mac, go to Finder > iCloud Drive. On your iPhone, iPad, or iPod touch, go to the Files app. On a PC with iCloud for Windows, go to File Explorer > iCloud Drive.

If you still don't see the latest changes or you see an "in-progress change" icon or the iCloud icon  in the notification area (system tray), try to save a new document to the iCloud Drive folder. Then check the iCloud Drive folder to see if the changes appear.

If it is isolated to this one file, how often does it happen?

If you duplicate the document, does the same thing happen with the new file?

Do you use other devices to make changes to files in iCloud?

Thank you for using Apple Support Communities. Have a nice day.
