How can a beginner build a simple JSON save editor?

A game-specific save editor usually isn’t a realistic first programming project. You’ll need to learn file handling, JSON parsing, how to locate the data you want, and how to preserve the exact format the game expects. There may also be existing tools or documentation from players who already understand this game’s save format. As practice, try building a tiny JSON editor for your own sample data first, such as changing a name or score in a simple test file.

A good learning sequence would be: install Python, learn the basics, practice opening and saving text files, study JSON objects and arrays, then write a program that displays and changes one known value. Only after that should you work with a copy of the game’s save. If the goal is mainly to learn programming, editing a simpler format such as music metadata may be less frustrating than reverse-engineering a commercial game save.

Visual Studio Code is perfectly fine for this, but the editor itself won’t replace learning programming. Start with basic Python, especially variables, conditions, functions, and reading and writing files. Then learn how to load JSON, change a value, and save the result using Python’s built-in JSON library. Make backups before testing anything on a real save.
