Excel not syncing

Saving the workbook on your iMac does not automatically make that copy available in Excel on your iPad. The key question is where the file was saved and whether both devices are opening the same cloud copy. First, keep a backup of the updated workbook on the Mac. Check its save location: if it is only on the Mac’s local drive, save or upload it to OneDrive or your organization’s SharePoint location. If it is already there, open that location in a browser and confirm the latest edits are present. That separates a Mac upload problem from an iPad opening problem. On the iPad, sign in with the same account and open the workbook through its actual cloud folder rather than the Recent list. Avoid overwriting the newer file with an older iPad copy.
