To reverse the rotation of your text and display it normally, simply go back to the “Alignment” tab on the “Format Cells” dialog box and enter “0” (that’s a zero, not the letter “O”) in the “Degrees” edit box.

The button turns black to show that the option is on and your text will look like the first cell in the image below once you click “OK” on the “Format Cells” dialog box. If you want the text to be vertical in a cell (each character takes up one line), click the box to the left of the semicircle angle box in the “Orientation” but (the box with the word “Text” in a vertical format). If you know the specific number of degrees you want to rotate the text, type the number directly into the “Degrees” edit box, or use the spinner arrow buttons to select a number. The number of degrees of the rotation displays in the “Degrees” edit box. To rotate the text, click on any point along the semicircle in the “Orientation” box. The “Alignment” tab automatically displays. For more fine-tune control when rotating your text, highlight the cells containing the text you want to rotate and click the “Alignment Settings” button in the lower-right corner of the “Alignment” section of the “Home” tab.
