Formateur JavaScript

Make Minified & Génèred JavaScript Readable

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

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

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

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

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

Learning from Examples: Found code on GitHub or in documentation that's minified? Formate it to study Comment ça marche.

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

One-Click Copy

Once Formateted 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 Formateted Code

The Formateter 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

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

Completely Traitement local

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