Hi Ryan,
You can set the orientation (rotation) of the text inside the cell by using the Rotation property of the CellStyle object. Please refer the following code snippet that illustrates the above:
[C#]
//Text Orientation Setting
sheet.Range["A1"].CellStyle.Rotation = 60;
sheet.Range["A2"].CellStyle.Rotation = 90;
Please refer the following sample which implements the above said feature:
Orientation.zipPlease take a look and let me know if you have any other questions.
Best Regards,
Melba
