Stop sharing a spreadsheet in Numbers on Mac
If you’re the owner of a spreadsheet that’s shared with others, you can stop sharing it to prevent anyone from viewing or editing it.
Tip: If you expect to temporarily pause sharing for a group, start your collaboration in the Finder, on iCloud.com, or on Box.com. (If you stop and restart sharing inside of Numbers, all previous activity information may be lost.)
Go to the Numbers app on your Mac.
In a shared spreadsheet, click in the toolbar.
Click Manage Shared Spreadsheet.
Click Stop Sharing.
An alert asks if you really want to stop sharing the spreadsheet. Click Continue to confirm.
Anyone who has the spreadsheet open when you stop sharing receives an alert. The spreadsheet closes when they dismiss the alert, and the spreadsheet is removed from their iCloud Drive.
The original link to the spreadsheet no longer works, unless you later share the spreadsheet again and set the access to “Anyone with the link.” If the access is set to “Only invited people,” the original link works only for people you reinvite to the spreadsheet.
Note: If you’re the owner of a shared spreadsheet and you move it to another location, the link is broken, and participants lose access to the spreadsheet.
