Toolverge

JavaScript Beautifier

A JavaScript beautifier re-indents minified or single-line JS so you can read it while debugging. Toolverge uses a heuristic, brace-depth formatter — not a full AST parser — so it works instantly client-side without a build step.

82 → 97 bytes

function greet(name) {
  if(!name) {
    return "Hello, guest!";
}
  return "Hello, "+name+"!";
}

How it works

  1. Paste minified or single-line JavaScript into the box.
  2. The formatter scans the code once, tracking strings, template literals, regex literals, and comments so brace characters inside them are ignored.
  3. Read the re-indented result below with a before/after byte count.

Formula Indentation depth increases after "{" and decreases after "}"; statements break after ";".

Frequently asked questions

Is this a real JavaScript parser?

No. It is a heuristic, brace-depth re-indenter, not an AST-based formatter like Prettier, so unusual syntax may format imperfectly.

Will it break my code?

It only changes whitespace and line breaks outside strings, template literals, regex literals, and comments — it does not rewrite logic.

Does it minify JavaScript too?

No. Use the JavaScript minifier for that; this tool does the opposite, expanding code for readability.

Does it support modern syntax like arrow functions and template literals?

Yes, since it works at the character level rather than validating specific syntax constructs.

Is my code uploaded anywhere?

No. Formatting runs entirely in your browser; Toolverge does not send your code to any server.
