Use vertical text in Numbers on Mac
Numbers supports vertical text in shapes and text boxes, so you can enter and edit text from top to bottom, such as in Chinese, Japanese, or Korean. Each new line appears to the left of the one before it.
To use vertical text, your spreadsheet must be formatted for Chinese, Japanese, or Korean, or you must have at least one of these languages on your device’s preferred language list. See Create a spreadsheet with the formatting of a different language and Change a spreadsheet’s language and formatting.
Add vertical text to a text box or shape
You can turn vertical text on or off in text boxes and shapes at any time.
Go to the Numbers app
on your Mac, then open a spreadsheet.Control-click the object you want the vertical text in.
Choose Turn On Vertical Text.
If the object already contains text, it becomes vertical and any additional text you add is vertical. If the object didn’t already contain text, any text you add is vertical.
To make the text horizontal again, Control-click the object, then choose Turn Off Vertical Text.
Fit characters horizontally in vertical text
You can fit two to four characters horizontally within vertical text. This is useful for writing a few Latin characters, such as numbers, so they can be read from left to right.
Go to the Numbers app
on your Mac, then open a spreadsheet.While writing vertical text, select two to four characters you want to rotate.
In the Text tab of the Format
sidebar, select 
, then choose Rotate to Horizontal.When editing the horizontal characters, you can make all of the characters bold, italic, and so on, but you can’t edit the individual characters separately.
If you want the horizontal characters to appear vertically again, delete the characters and reenter them.
Make characters full width
You can change text to full-width, upright characters.
Go to the Numbers app
on your Mac, then open a spreadsheet with vertical text.Select the vertical text you want to make full width.
In the Numbers menu bar at the top of your screen, choose Edit > Transformations > Make Characters Full Width.
Tips for using vertical text
