Excel spreadsheet cells Every little box in a spreadsheet grid is a cell, which can contain numbers, letters, colors, and formulas.

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.

Unfortunately, you won’t find the “edit this cell” command listed in Excel’s keyboard customization section, so there’s no apparent way to change the shortcut.
