What is "diffenginex"

DiffEngineX compares two Excel spreadsheets and reports their differences. It compares cells (formulae, constants and calculated values), comments, defined ranges (names) and Visual Basic for Applications (VBA) macros. Before a cell-by-cell comparison, similar rows and columns between two spreadsheets have to be aligned by the insertion of blank rows/columns. Otherwise identical cells between two workbooks will be missed. It runs on Microsoft Windows.
