If you create a spreadsheet that you want to use again as a model for other spreadsheets, you can save it as a template. Creating your own template can be as simple as adding your company logo to an existing template, or you can design a completely unique template.
You can add your custom template to the template chooser, or save it as a file to share with others or to install and use on your iOS device.
If you want to install a custom template on an iOS device, save your template to iCloud, iTunes, a WebDAV server, or send it as an email attachment. Then, open it on your device.
Choose File > Save as Template (the File menu is at the top of your computer screen).
Click one of the options:
Add to Template Chooser: Type a name for the template, then press Return. Your template appears in the My Templates category in the template chooser.
Save: Type a name for the template, then choose where you want to save it.
If you save it to iCloud, the next time you open Numbers on your iOS device, the template appears as a downloadable file in the spreadsheet manager.
If you save a template to a web server or upload it to webmail, it must have the file extension .nmbtemplate.zip to install it and use it in Numbers on your iOS device.
If you saved the custom template to your computer or to a server, you can quickly install it. Templates saved to iCloud appear in the spreadsheet manager in Numbers and are identified by a template badge.
Double-click the template file (it has the file extension .nmbtemplate), then click Add to Template Chooser.
You can set Numbers to always open a new spreadsheet from the same template instead of from the Template Chooser. Choose Numbers > Preferences (from the Numbers menu at the top of your computer screen). In the General pane of preferences, select “Use template,” then click Change Template to select a template.
In the template chooser, Control-click the template name, then choose Rename or Delete.
If you’re renaming, type a new name, then press Return.
Custom templates always appear in the My Templates category in the template chooser. You can’t rearrange templates; they always appear in the order in which they were added.
