Excel Text Boxes

TextBox elements are special rectangular areas that contain text, they are part of the shape elements accessible through the ExcelShape.Text property.

With the ExcelShape object, you can specify the element's size, location, and geometry (for more information, see the Shapes example), but with the TextBox object, you can specify the text content and text formatting.

The following example shows how you can create and customize text boxes and their content and add them to an Excel worksheet.
