Create your first spreadsheet in Numbers for iCloud
To create a spreadsheet, you first choose a template to use as a starting point. Templates are designed for some of the more common types of spreadsheets (such as personal budgets, invoices, or school schedules), and they use coordinated fonts, colors, and graphic elements for a unified look. Most templates also have placeholder elements like title text and tables that you can replace with your own content.
For example, if you want to set up a budget, you could choose one of the budget templates and add your own data to the placeholder tables.
In the spreadsheet manager, click the Create Spreadsheet button
in the toolbar.Double-click a template.
To design your spreadsheet from scratch, choose the blank template.
Note: If you want table and chart data in this spreadsheet formatted according to the conventions of a different language, choose a different language in the top-right corner of the template chooser. See Create a spreadsheet with the formatting of a different language.
Do any of the following:
Add data to a blank spreadsheet: Click a cell, then type. To add a formula, click a cell, type an equal sign (=), then choose a formula from the Functions Browser in the sidebar on the right.
Replace placeholder chart data: You need to edit the table containing the data for the chart. Click a table cell, then enter your own data. The chart updates automatically.
Edit text: To replace placeholder text, click the text, then type. To edit text you’ve typed, select the text, then type. To format the selected text, use the controls in the sidebar on the right.
Add new text, charts, or other objects: Click an object button in the toolbar.
Note: To add a chart, you must first have a table in your spreadsheet that contains the data that the chart will display. See Add or delete a chart in Numbers for iCloud.
Add or delete a sheet: Click the Add button
in the upper left to add a new sheet to this spreadsheet. You can add multiple sheets (or tabs) to a spreadsheet to help you better organize your information. To delete a sheet, Control-click the tab for the sheet at the top of the spreadsheet, then choose Delete.
Undo or redo a change: Click the Undo button
or the Redo button 
in the toolbar.Enlarge (zoom in) or reduce (zoom out) your overall view of a spreadsheet: Click the Zoom pop-up menu in the toolbar, then choose an option.
Click the spreadsheet’s current name at the top of the spreadsheet, type a new name, then press Return (on a Mac) or Enter (on a Windows computer).
Numbers for iCloud automatically saves your changes as you work, so you don’t need to worry about saving your spreadsheet manually.
To close the spreadsheet and return to the spreadsheet manager, move the cursor over the spreadsheet’s title at the top, then click the X that appears on the left side of the tab.
