Restore an earlier version of a spreadsheet in Numbers for iCloud
Numbers for iCloud periodically saves versions of your spreadsheet. If you want to return to a previous version (for example, because you deleted content you decide you still need), you can restore an earlier version.
Note: If you or someone you’re sharing a spreadsheet with reverts to an earlier version of the spreadsheet, everyone sharing the spreadsheet sees the earlier version. See the Intro to collaboration in Numbers for iCloud.
Open the spreadsheet, click the Tools button in the toolbar, then choose Browse All Versions.
In the Version History popover, select the spreadsheet you want to restore.
If you’re not sure which version you want to restore, select a spreadsheet, then click Preview. To compare it with another version, select another version, then click Preview again.
The preview is view-only (you can’t make any changes to it). To download or print a copy, click the Tools button at the top of the preview window, then choose an option.
Click Restore at the bottom of the Version History window.
Tip: You can also click Restore in the top-right corner of a spreadsheet you’re previewing.
The current version is replaced with the selected version.
If you accidentally delete a spreadsheet (or folder) entirely, you may be able to get it back by recovering it.
