how to compare a list of data that is same as the main data sheet

[Nxam]

i have some data sheets that is need to be compared with a main data sheet
and if its same, the numbers thats equal to be marked (eg:being highlighted
or colored)...
is there a way to do this.
Thanks in advance

Yes it can be done, but it is not clear what you want
Are you matching values in a range eg does the value appear anywhere in the sheet or are you comparing the same cell in each sheet? Or do you mean something else!
