Compare 2 files excell

We need a software or little app running on windows or, even better, on our linux server that compare 2 files excel like the ones attached. The comparison must be done on the column E of the file ft edelweiss and the column B in the file modello documento. We need to know if in the 2 files there are the same numbers and which numbers there are in a culumn and not in the other and viceversa. For any further information do not hesitate to contact me. Thanks, Regards, Marco
