Check this out: Javascript obfuscator This tool transforms your original JavaScript source code into a new representation that's harder to understand, copy, re-use and modify without authorization. The obfuscated result will have the exact functionality of the original code.

I find this pretty helpful: JSON Formatter It's a web-based tool to view, edit, format, and validate JSON with various mode available such as a tree editor, a code editor, and a plain text editor.
