Yes, I already found the class type in the save file.
I haven't continued to research the structure of the save file, but things like inventory, level, health, mana, quests that completed, basically anything that changes with your character is saved on the save file and editable.
To find the values that I haven't found yet like these mentioned above it takes more time because I have to level up and find the changed values in the file, so it takes time.
