Source code of Power Bi Pbix File

You can rename the pbix file to zip and extrac the zip file to get to the source code files.  If you do decide to change the xml code, I recommend pulling the file out of the zip, modify it and drag it back in the zip file, rather than extracting the whole zip file.
