If your text exceeds the size of a cell, the text automatically spans into multiple columns. Some people find this a nuisance and prefer to wrap the text in a cell. Personally, I always wrap text because I find it difficult to read text that spans multiple columns.
It’s easy to wrap text in Excel 2007. Simply select the cell that you want to wrap (you can also select multiple tabs). Click Home on the Ribbon and select Wrap Text.
That’s all there is to it.
