Code Beautifier

Format code using Prettier. Supports JS, TS, CSS, HTML, JSON, YAML, Markdown, and GraphQL.

What is Code Beautifier?

Code Beautifier formats and beautifies source code in 8+ languages using Prettier, the industry-standard code formatter. It supports JavaScript, TypeScript, CSS, HTML, JSON, YAML, Markdown, and GraphQL — all powered by Prettier plugins loaded directly in your browser.

How to Use

  1. Select your programming language from the dropdown
  2. Paste your unformatted code into the editor
  3. Click Format to beautify the code with Prettier's opinionated formatting rules

Use Cases

  • Formatting minified JavaScript or CSS back into human-readable code
  • Standardizing code style before pasting into documentation or blog posts
  • Cleaning up inconsistently indented code copied from Stack Overflow or GitHub
  • Quickly reformatting YAML or JSON configuration files

Privacy & Security
