XP versus Vista spreadsheet

[S S]

I have sent a spreadsheet to a client, they are not to clever with PC. I
have sent from office 2000 using windows XP, they have Vista but not sure if
they have office, assuming they do are the two going to be compatible? They
cant open the spreadsheet.

Is there a free download to convert if this is the issue?

thanks

Later version are compatible with all earlier versions

Go to microsoft.com and search for excel viewer, it's clear that they don't
have excel or else they would be able to open it
