DiffEngineX will compare VBA code if the option Compare Visual Basic Code / Macros is selected from the Options dialog. xla and .xlam files need to be converted into .xls and .xlsm files first. Click here for instructions.
Currently VBA macros in referenced add-ins are not loaded for the purposes of execution during the process of spreadsheet comparison. If you have cell formulae referencing user defined functions written in Visual Basic, you may want to contact us for our special build of DiffEngineX which loads Visual Basic for Applications macros.
