Форматировщик JavaScript

Make Minified & Генерируетd JavaScript Readable

Minified JavaScript is Сжимаетed into a single line for production efficiency, but it's unreadable when you need to debug or inspect it. Генерируетd code from bundlers, transpilers, or code generators often lacks Форматируетting. Trying to understand function a(b){return c(b.d)?e(b.f):null} is painful compared to properly Форматируетted code.

This JavaScript Форматируетter instantly beautifies any JS code, applying consistent indentation and line breaks. Read minified bundles, debug Генерируетd code, and understand code structure at a glance.

Customize Форматируетting Style

Indentation Options: Choose 2-space (compact, popular in modern projects) or 4-space (traditional, readable for complex nesting).

Brace Style: Select how opening braces are placed relative to statements:

• Collapse: Braces on same line as control structures (compact)
• Expand: Braces on separate lines (readable, common in some style guides)
• End Expand: Opening brace on same line, closing on new line (balanced approach)

These options let you match your team's coding standards or project conventions.

What Форматируетting Does

• Breaks code into readable lines at logical boundaries
• Applies consistent indentation for nested blocks
• Separates statements for clarity
• Preserves logic and functionality while improving readability
• Makes variable names, function calls, and control flow visible

Common Developer Scenarios

Debugging Minified Code: Браузер throws an error in minified code? Форматирует it to find the bug. Errors in minified bundles point to line 1, column 50000—not helpful. Форматирует the bundle and locate the actual problem.

Reading Генерируетd Code: Transpilers (Babel, TypeScript), bundlers (Webpack), and code generators produce valid but unФорматируетted output. Форматирует it to understand what was Генерируетd.

Code Review of Build Artifacts: Need to review what a bundler or build tool produced? Форматирует the output for human inspection.

Learning from Examples: Found code on GitHub or in documentation that's minified? Форматирует it to study Как это работает.

Preparing Code for Analysis: Before analyzing code complexity, performance, or security, Форматирует it for easier inspection.

One-Click Copy

Once Форматируетted to your satisfaction, copy the output with a single click and paste it directly into your editor, documentation, or analysis tools.

Works with Minified & Poorly Форматируетted Code

The Форматируетter is forgiving. It handles:

• Single-line minified code
• Multi-line code with irregular indentation
• Missing whitespace and line breaks
• Nested structures
• All valid JavaScript syntax

Syntax Highlighting

Форматируетted code displays with syntax highlighting, making it even easier to read. Keywords, strings, comments, and operators are visually distinguished.

Completely Локальная обработка

Форматируетting happens entirely in your браузер using the js-beautify engine. Your code never leaves your machine, so you can safely Форматирует proprietary code, internal utilities, or any sensitive JavaScript.
