Saving a Copy of a Spreadsheet
If you want to duplicate your open spreadsheet, you can save it using a different name
or location.
To save a copy of a spreadsheet in Mac OS X v10.7 (Lion) or later:
1 Choose File > Duplicate.
An untitled copy of the spreadsheet is created. Both copies remain open on your
desktop for you to view or edit.
2 Close the window of the untitled copy, type the spreadsheet’s name, and then choose
a location from the pop-up menu.
3 Click Save.
To save a copy of a spreadsheet in Mac OS X v10.6.x (Snow Leopard) or earlier:
Choose File > Save As and specify a name and location.
m
The spreadsheet with the new name remains open. To work with the previous version,
choose File > Open Recent and choose the previous version from the submenu.
You can also automate creating a backup version of the spreadsheet every time you
save, retaining the name and location of the original, but with the words “Backup of”
preceding the filename. See “Automatically Saving a Backup Version” on page 35.
Finding an Archived Version of a Spreadsheet
If you saved your spreadsheet multiple times on Mac OS X v10.7 (Lion) or later, all the
saved versions are automatically archived. You can browse the archive to identify any
earlier version that you want to restore or reference. After you identify the archived
version that you want, you can restore it as a fully editable copy, or you can just extract
from it any text, images, or document settings that you want to use again.
To browse and restore archived versions of your spreadsheet:
1 Open the spreadsheet for which you want to access older versions, and hold your pointer
over the name of the spreadsheet at the top of the Numbers application window.
A triangle appears.
2 Click the triangle and choose Browse All Versions.
