How to Write Sideways in Excel

1. Open Excel to a blank spreadsheet or open an existing spreadsheet.
2. Click a cell you want to add text to. Click the 'Home' tab on the ribbon if it is not already open. Click the 'Text Orientation' button in the Alignment group. The button has no name but shows the letters 'ab' with an arrow underneath pointing diagonally.
3. Select the type of rotation you want. You can select 'Vertical text' to have letters appear vertically one at a time in your cell or select 'Rotate up' or 'Rotate down' to face your text left or right.
4. Type the text as you would normally. Press 'Enter' to see your text align sideways.
