To set this up, first select the range of cells you’d like to apply your formatting to.
Make sure the “Format” pane is open, but if you don’t see that sidebar on the right, click “Format” in your toolbar. Then under the “Cell” tab, you’ll see the “Data Format” drop-down.
Under that drop-down, you have a bunch of options.
See? There’s just so much to play with. You could pick “Number” and control the decimal places the program will insert, say, or you could use the “Currency” option to automatically add in dollar signs. “Pop-Up Menu” will let you configure just that if you want a range of cells to allow only a few predefined choices.
Or if you pick “Checkbox,” you can add your own checklist to the cells you selected.
And finally, there’s “Create Custom Format.” In my first screenshot, I selected some cells with numbers in them. Using the power of a custom format I set up…
…I told those cells to add in parentheses, hyphens, and spaces to make them look like phone numbers, all nice and neat-like.
It’s just so much easier to type without having to worry about the punctuation or the separators!
So anyway, I think it’s well worth checking this out if you use Numbers, especially if you do a lot of data input. For every moment I don’t spend typing in a dollar sign, I’m gonna go do something fun! OK, that’s not a lot of time, but maybe I could spend those seconds thinking about everything I could be doing that’s not putting stuff into a spreadsheet. Oh, man, I just depressed myself.
