Change Excel Icon

Hi,

I have just created an excel sheet but would now like to put a company logo as the image icon istead of the excel sheet.

So is there a way of changing the excel icon?

For an example you can change internet explorer icon by right click properties and change icon.

Can someone let me know if this is possible and what I need to do. Also what type of file it needs to be, i think it may need to be an exe. so if anyone knows how to create them it would be very helpfull.

Thanks,

Leigh
