How to Wrap Text in Excel 2007
In Microsoft Office Excel 2007, if the text you type is too long to be displayed fully in a cell, you can easily set the text to wrap. This setting enables the cell (and the rest of the row) to expand automatically so that the content of the cell is always visible.
1. Click in the cell that you want to wrap.
2. On the Home tab, in the Alignment section, click Wrap Text.
