Code Formatter & Beautifier Tools
Code formatters restructure source code with consistent indentation, spacing, and line breaks, making it easier to read, review, and debug. Whether you are beautifying minified JSON from an API response, cleaning up a SQL query before a code review, or minifying CSS for production, these tools do it in one click.
All formatters work client-side in your browser with no data uploaded to any server. Paste your code, choose your preferred indent style (spaces or tabs) and width, and get perfectly formatted output. Each tool also supports minification to reduce file size for production deployments.

Frequently Asked Questions
- Does formatting code change its behavior?
- No. Formatting only changes whitespace, indentation, and line breaks. The logic and output of your code remain identical. Minification removes whitespace but also preserves functionality.
- What indent options are available?
- Most formatters let you choose between 2-space, 4-space, or tab indentation. SQL and JSON formatters also support custom indent widths for team-specific style guides.
- What's the difference between formatting and minifying?
- Formatting (beautifying) adds whitespace and indentation for readability. Minifying removes all unnecessary whitespace to reduce file size. Both operations are reversible — you can beautify minified code and minify beautified code.
- Can I format partial code snippets?
- Yes. Paste any valid fragment and the formatter will process it. For HTML and XML, fragments that are not fully closed will still be indented correctly based on their nesting level.
