If you find yourself wanting to profile VBA code from Excel, your options are limited. There are currently some approaches out there, but none are truly as easy as you want. The main problem is simple enough: VBA does not provide the necessary hooks to add a profiler without touching your own code. This means that you are required to modify your own code to add a profiler. This means that unless you really need to profile your code, you will likley avoid the burdern. To make this process a little eaiser, I built a quick tool to automatically add profiling code ot an existing VBA project. The biggest feature here is that the code will run without additioal references or any extra code withing your project. It works by parsing your code and adding Application.Run commands which call out to the same spot that gneerates the code. That means: if you are able to load the addin which can add the profiling code, you can already support the profiling. There is a ismple interface to add code to a specific module. From there, you run your code like nromaly, and the addin will take care of tracking the calls. The addin handles the task of automatically tracking the call stack and adding adn removing groups. Once your code has run, you hit a keyboard shortcut and the results are opened in a new workbook.
