Like some of you when I first went to port my mod to 1.12.2 I threw up a little bit in my mouth when I saw all the shifting to .json files I would have to do, so instead I decided to write a program that makes the process a bit more painless. It allows you to be able to more quickly turn out some of the simple and repetitive recipes that could take place in mods both big and small though the help of a UI. The JSON file will be generated on your desktop, allowing them to be quickly moved to where they need to be.
Note: most of the fields by which you can type in will be added to the generated json file verbatim, so if you do make a typo make sure to correct it in the file. Secondly the 'Keys' that are used for the shaped recipes follow a very specific pattern: this being the Identifying pattern key such as A, W, or S shown above. Followed by and underscore and then the item you wish for that letter to represent.
