Try changing the font of the cell concerned:

Try font like "terminal", "WST_Engl", "Fixedsys"

these fonts will display zero with a diagonal line from the top right to the
bottom left of the number.



"DISPLAY ZERO WITH LINE THROUGH IT" wrote:

I have government reports that need to show a zero with a line through it so
they are VERY distinguishable from the letter "O". I cannot find a format
that displays this. I need this ASAP! Can anyone help me please?!
