Excel cells will hold your text as you enter them, however, if the text is long, it can run into other cells. You will need to make the Excel cells fit the text.

Open your spreadsheet in Microsoft Excel 2003 and double-click the cell in which you want the textual white space to appear. Press the "Spacebar" to enter single-character spaces.

Open the Excel worksheet for which you want to alter the column width. Click on the Home tab in the Excel ribbon. Go to the Cells group and click on the "Format" icon to reveal the Cell Size menu.
