Minified code, copy-pasted snippets, or code from an inconsistent source can end up dense and hard to read — no consistent indentation, everything crammed onto a few lines. Beautifying it restores clear structure so you can actually read and understand it.

When you need to beautify code

• Reading minified JavaScript or CSS pulled from a live website
• Cleaning up a snippet copied from a chat, email, or forum post with lost formatting
• Making inconsistently indented code from multiple contributors uniform
• Preparing a code snippet to share cleanly in documentation or a report

How to beautify code, step by step

1. Open the Code Beautifier.
2. Paste the code you want to format.
3. The tool adds consistent indentation and line breaks.
4. Copy the cleaned-up result.

Tips for working with beautified code

• Beautify before debugging minified code pulled from a production site — it's much easier to trace logic once it's properly indented.
• Check for consistent style afterward if you're merging code from multiple sources, since beautifying standardizes formatting but won't fix stylistic choices like variable naming.
• Keep the original if you need it exactly as-is for something like a checksum comparison — beautifying changes whitespace, which would affect an exact-match comparison.

Common questions

Will beautifying change what the code does? No — only whitespace and indentation change; the logic and behavior of the code stay the same.

Does this work for any programming language? It handles common web and general-purpose languages well; highly specialized or unusual syntax may format less predictably.

Is this the same as formatting SQL? For SQL specifically, the SQL Formatter is tuned for query structure; this tool is for general-purpose code.
