How To Use

Paste Code: Select your language from the dropdown (HTML, CSS, JS, or JSON) and paste your unformatted or minified code in the left box.
Set Indentation: Choose how you want your code spaced out. Standard developers use 4 spaces, but React/Vue devs often prefer 2 spaces.
Beautify & Copy: Click "Beautify Code" to instantly format it. Then, use the "Copy Code" button to grab the clean result.

Why Use This Tool?

Readability: Minified code (like `script.min.js`) is impossible to read. This tool acts as an "Unminifier", restoring line breaks and spaces so you can understand the logic.
100% Offline Privacy: Your proprietary code is never sent to a server. The formatting engine runs securely inside your own browser using JavaScript.
VS Code Engine: Powered by Monaco Editor, providing you with syntax highlighting and auto-completion just like desktop software.

Frequently Asked Questions

Can this tool format broken or syntax error code?

The beautifier will try its best to organize the structure based on brackets and tags. However, if your JSON is invalid or missing quotes, it might fail to format perfectly. It's recommended to fix major syntax errors first.

Is it safe to paste confidential company code here?

Yes, absolutely! Because this tool uses a client-side algorithm to process the text, your code never leaves your computer. It is 100% safe for confidential data, API responses, and proprietary logic.
