Minified JSON, one-line SQL, opaque type definitions — code is meant to be read, but it rarely arrives that way. The tools in this group format, beautify, and re-shape source so you can review it before shipping. JSON Formatter pretty-prints API responses. SQL Formatter applies consistent casing and indentation. JSON to TypeScript generates type definitions from a sample payload. HTML/CSS/JS Beautifier untangles minified bundles. JS Obfuscator does the inverse when you need to ship code without revealing intent. Markdown Preview renders content the way GitHub will.
