Do you mean files written in Excel, with the extension .xls or .xlsx? I've never tried to "compare two files", but (with the Report Generation Toolkit) it is easy enough to simply read the data from the two files (in LabVIEW) and ask if they contain the same values.
There are numerous posts on the Forum (and probably on the Web) discussing how to read Excel data with LabVIEW. I presume that you know how to test two arrays to see if they are identical. Have you written any LabVIEW Code? Does it work? If it does, then you've solved your own problem. If it does not, attach your VI (or VIs) and describe the problem you are having.
