If excel is updating some sort of meta data within the file,
which changes
the MD5 of it every time it is viewed. I can't think of any
modules you
could use externally to do what you want to do.
Maybe you can dump that row/column data of the table and
generate a MD5 sum
off of that to see if any of the internal data points have
actually changed.
