IconVault's Code Formatter cleans up messy code with proper indentation, brace placement and spacing for JavaScript/TypeScript, CSS, HTML, JSON, YAML and Markdown. Paste your code, hit format, and copy the tidy result. It is free and runs fully in your browser, so your code never leaves your machine.

This is a lightweight formatter, not a full Prettier port: it normalizes indentation, brace newlines and spacing so unreadable minified or hand-mangled code becomes readable again. It is ideal for quick cleanups, debugging pasted snippets and preparing code for docs. For project-wide enforced style, a dedicated formatter in your build pipeline is still the right tool.
