Hi Kelly.
The formulas (*not* in Excel spreadsheet format) are on Bruce Lindbloom's site (<http://brucelindbloom.com>):
Delta E (CIE 1976):
http://brucelindbloom.com/Eqn_DeltaE_CIE76.html
Delta E (CIE 1994):
http://brucelindbloom.com/Eqn_DeltaE_CIE94.html
Delta E (CIE 2000):
http://brucelindbloom.com/Eqn_DeltaE_CIE2000.html
Delta E (CMC):

I have been able successfully to translate some of these formulas into expressions inside Excel spreadsheets, and I will send you a copy offline later in the day.
Best regards.
