Use iCloud with Numbers
iCloud stores your spreadsheets and keeps them up-to-date across your iOS devices, the web, and your computer so that you always have the most current versions at hand, no matter which device you used to make your latest edits.
You can edit Numbers spreadsheets in a web browser using Numbers for iCloud beta on supported web browser from a Mac or Windows computer.
Spreadsheets you create using Numbers for iCloud beta are automatically available in Numbers on your Mac and iOS devices that are set up to use iCloud—and vice versa: if you create a spreadsheet using Numbers on an iOS device or a Mac, it appears automatically on the web in Numbers for iCloud beta.
For help using Numbers for iCloud beta, click the Help button in the Numbers for iCloud beta spreadsheet manager, then choose Get Help. If you’re working in a spreadsheet, choose Tools > Help.
Set up Numbers to use iCloud
Open System Preferences on your Mac, then click iCloud.
Sign in using your Apple ID, or request a new Apple ID, then sign in.
Select the Documents & Data checkbox, then click Options.
Select the Numbers checkbox, then click Done.
Here are a few things to keep in mind about using iCloud to manage your spreadsheets across devices:
If you edit and close a spreadsheet when you’re not connected to the Internet, the word “Waiting” appears under the spreadsheet thumbnail in the Open panel. The next time you connect to the Internet, the edited spreadsheet is saved to iCloud.
If you edit a spreadsheet on more than one device before saving any of your changes to iCloud, you will get conflicts. To avoid conflicts, make sure your edits are always saved to iCloud before editing the same spreadsheet on another device. If you do get a conflict, you can choose to preserve any or all of the spreadsheets that you edited.
If you delete a spreadsheet, it’s deleted from iCloud and from Numbers on all your devices.
If you organize your spreadsheets into folders on one device, you see the same folder organization on all your devices.
If you change the title of a spreadsheet on one device, the title is changed on all your devices.
If you add a password to your spreadsheet on one device, you need to enter the password to open the spreadsheet on all your devices.
To share a spreadsheet on iCloud, you need to save the spreadsheet to iCloud.
