Beautify or Minify Code in 17 Languages
Code formatters transform messy or minified code into cleanly structured sources that are easier to read and maintain. Whether you are working with JavaScript, Python, SQL, or Rust, consistent formatting reduces cognitive load and prevents bugs caused by unclear structure. Toggle minify mode to compress code for production deployment with one click.
Why Format Your Code?
Consistent formatting catches syntax errors by revealing mismatched brackets and unexpected structure. It saves code review time by removing style debates — reviewers focus on logic instead of spacing. Most importantly, properly formatted code is searchable and navigable, making it easier to find specific functions or debug issues.
Language-Specific Formatting Rules
JavaScript/TypeScript/Java/C#/PHP: inserts line breaks, formats object literals, and aligns function bodies with brace-based indentation. HTML/XML: indents nested tags, places closing tags on new lines, and handles self-closing tags. CSS: formats rules into separate blocks with properties on their own lines. JSON: validates before formatting and handles large nested structures. SQL: breaks queries at SELECT, FROM, WHERE, and other major clauses with consistent indentation for sub-clauses.
Frequently Asked Questions
Q:What languages does this code formatter support?
This formatter supports JavaScript (JS), TypeScript (TS), HTML, CSS, JSON, Python, XML, SQL, YAML, GraphQL, Rust, Go, Java, C#, PHP, Ruby, and Bash. Each language has its own formatting rules — JS/TS/Java/C#/PHP use brace-based indentation, HTML/XML format tags with proper nesting, CSS formats rules into blocks, Python/Ruby/Bash use keyword-level detection, SQL breaks at major clauses, and JSON validates structure while formatting.
Q:How does the formatter handle syntax errors?
The formatter does best-effort formatting to make code readable even with minor syntax issues. For JSON, invalid JSON shows a clear error message — only valid JSON is formatted. For code, comment-aware bracket tracking prevents strings and comments from affecting indentation. For production code, always run the formatter on valid syntax.
Q:Can I get minified output instead of beautified?
Yes. Toggle the "Minify" option to produce compact output instead of beautified code. Minifying removes unnecessary whitespace, newlines, and comments while preserving functionality. Use beautify mode for readability and minify mode for production-ready compact output. The stats bar shows estimated size savings.
Q:Does formatting preserve all my code structure?
Yes. Formatting only adjusts whitespace and line breaks — it does not change variable names, function definitions, or program logic. The output code runs identically to the original. Use the indent size selector to match your team standards (2 or 4 spaces).
