What this tool does

JavaScript Formatter gives you a fast, focused way to normalize indentation around JavaScript blocks without executing code. Everything runs locally in this tab.

The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.

Example

const greet=(name)=>{if(name){return `Hello ${name}`;}return "Hello";};

Limitations

• Review important output before using it in production.
• Very large inputs remain subject to browser memory limits.
• This lightweight formatter normalizes braces and semicolons; it is not a full JavaScript parser.
