Hello, arienfire001. The previous responses are correct. None of those stew recipe guides were developed by LDW, but were submitted by people who played the game. I usually recommend the free Excel viewer that Microsoft offers for people who just want to view them, but if you're interested in being able to edit them there are several free alternatives for that, too, such as the software offered at
http://www.openoffice.org. Of course several of the stew guides are in pdf format, for which Adobe offers a free reader.
