4 years ago, we had to customize the xer parser for a client, that work end up as Xer Reader, turn out the file was very popular, but unfortunately, as it was written in VBA, users get all kind of different errors, and I was not able to provide a proper support.
now I am trying to rewrite the same Excel Macro but now using PowerBI, the file is hosted in github
in order to open a pbix file, you need PowerBI Desktop, it is a free download
I think it will be an interesting experience, some stuff are much easier using VBA, and there is no equivalent in PowerBI, I will try to document the progress.
in the main time here is my progress so far
