Hi,

This depends on what you mean by characters and what version.

Excel 2003 and earlier:
32,767 characters. Only 1,024 display in a cell; all 32,767 display in the
formula bar.
Formulas 1024

Excel 2007:
32,767 characters, all can be displayed in a cell.
Formulas 8192

If this helps, please click the Yes button.

Cheers,
