A consistent JavaScript style makes a small function or configuration object easier to review. The browser workspace parses source text and formats it without running your program.

Open the JavaScript Formatter to follow the workflow. Processing runs in your browser; the tool does not upload the input for conversion.

A practical workflow

  1. Paste JavaScript source. Use the example or load a UTF-8 source file.
  2. Choose indentation. Select two or four spaces for the formatted output.
  3. Format and inspect. Read the highlighted source and resolve parsing errors before retrying.
  4. Copy or download. Save the formatted source and review it in your project.

Try a concrete example

The following demonstration input is also available in the workspace. Replace it with your own data after checking the expected behaviour.

const user={name:"Ada",active:true};function greet(name){return "Hello "+name;}

With the default settings, the result is:

const user = { name: "Ada", active: true };
function greet(name) {
  return "Hello " + name;
}

Use source code rather than an entire HTML page

Paste JavaScript into this workspace. If you have a complete page with script tags, use the HTML Formatter for the page structure. A JavaScript parser cannot treat arbitrary HTML as ordinary JavaScript source.

Syntax checks do not establish correctness

A successfully formatted function can still contain a logic error, an unsafe operation or a missing dependency. Use your project tests and runtime checks after formatting. The tool is designed for presentation and review, not for proving the program safe.

Review automated changes with a diff

Formatting can move line breaks and add consistent punctuation or spacing. A difference view helps you distinguish those changes from a deliberate code edit. Keep the original source available when debugging line-number-sensitive logs or generated files.

If the result needs attention

Paste JavaScript source, not an entire HTML document. Your code is parsed as text and is never executed.

Read the exact error before changing the input. Keep a copy of the original, reduce the sample when investigating a large file, and use the destination application to verify that the result has the meaning you intended. The tool processes the supplied data; it cannot infer an unstated application schema or project requirement.

Use the Text Diff Checker to compare a saved result with the original. Keep transformation and application testing as separate steps so presentation changes are not mistaken for verified behaviour.
