Formateador JavaScript

Make Minified & Generad JavaScript Readable

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

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

Customize Formateating 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 Formateating 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: Navegador throws an error in minified code? Formatea it to find the bug. Errors in minified bundles point to line 1, column 50000—not helpful. Formatea the bundle and locate the actual problem.

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

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

Learning from Examples: Found code on GitHub or in documentation that's minified? Formatea it to study Cómo funciona.

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

One-Click Copy

Once Formateated 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 Formateated Code

The Formateater 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

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

Completely Procesamiento local

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