Thread: Compare two versions of a Project file

  1. #1

    Post Compare two versions of a Project file

    At one point or another, most Project users end up having to compare two Project files to find the differences. This can be a pain in the neck if you have to do it line by line. And writing a macro to do it is no fun either. So, don't do either one - use this macro already finished and tested. It creates a comparison file in Excel and highlights the differences in red. To install it, copy the code into a new module and add a reference to the Excel Object Library. Then load the oldest of the two files to be compared, and then the later one. Then start the macro and sit back until it finishes. Comparing two files has never been easier!

    Here it is - enjoy! Send me your comments or suggestions, please!

    Comment = "Wow I'll have to look at that in more depth."
    Suggestion = "Use Trim$ instead of Trim, it runs faster."

    Seriously though, you should make this a KBase Entry. Do you know how to do that?
    Cordially,
    Aaron

    I know this thread is quite dated, but I stumbled across the above macro and have brushed it up a little to run faster and. Thanks to the original author and my code is below (You need the Sub and the function).
