I highly doubt you'd ever get diff for XLS in a general or universal case. That format is so old and crusty that it's only really defined by what Excel will do

I highly doubt you'd ever get diff for XLS in a general or universal case. That format is so old and crusty that it's only really defined by what Excel will do with it.
XLSX, on the other hand, at least has to follow XML conventions and basic ZIP file structure, even if the open specification for the XML is really now a strict subset of what the current version of Excel will accept.
