Excel 2000 querry.
 

I have two files in Excel 2000.The second one is the
modified version of first file.The modifications are in
different cells.These modifications are in differnt types
like some cell values are changes since these are manual
entries.Some cells have formulae and these are modified in
the second file.
Now I wish to find out all the cells which are modified
and what exactly are the modifications as compared two the
first file?
Is there any option available in Excel 2000 or a utilty
program available to do this?
