GuildStats has a feature to allowing saving of a log file in a format called zULF, this format allows for saving space ( Making the log much simpler to share) and provides higher parsing speed then the native game combat logs.


The way to use this feature is simple:

  • Parse the log you want.
    In the menu "File -> Save combat log"


If you for some reason wanna build your own parser for this file format, go right ahread its a plain and simple format. Only thing to remember is that its gzip.
