Numbers
Delete a spreadsheet in Numbers on iPad
Important: If you turned on iCloud Drive for Numbers (in Settings on your iPhone or iPad), deleting a spreadsheet from iCloud Drive removes it from iCloud and from all other devices and Mac computers where you’re signed in to the same Apple Account.
Note: When you delete a spreadsheet that was shared with you, it’s deleted immediately from your device and can’t be recovered from Recently Deleted. If you later need to see the spreadsheet again, tap the link you received in the original invitation or ask the owner to send another.
