Three more tools implemented and the toolkit is now at 17.

Base64 encode/decode was the simplest one. Python has it built in with the base64 module, so it was mostly about building a clean submenu and making sure the output was readable instead of raw bytes. Same pattern as the encryption tool, encode() on the way in and decode() on the way out.

The JSON formatter took a bit more. It reads a file path from the user, opens it, parses the JSON, and prints it back with 4-space indentation. The important part was wrapping the whole thing in a try/except — if the file doesn’t exist or the JSON is malformed it gives a clear error message instead of crashing. Something I’ve been doing more naturally now without thinking about it.

Text case converter was probably the most fun. UPPER and lower are trivial, Title Case is one method call, but camelCase and snake_case required actually thinking through the logic, split by spaces, transform each word, join with different separators. Doing snake_case first made camelCase easier to see.

19 hours in. Still have regex tester, lorem ipsum, process killer, and menu polish left before this is ready to ship.
