Light formatter. Not Prettier. Adds indentation around braces and semicolons. Minify strips comments and whitespace. Validate only checks bracket balance; not a full JS parser.

How it works

Paste or import JavaScript

Paste JS text or import a .js file up to 10 MB. Unbalanced brackets are flagged live.

Format or minify

Format adds readable indentation (2 or 4 spaces). Minify removes comments and extra spaces.

Questions

What does JavaScript Formatter do?

It indents code for readability or minifies JavaScript by removing comments and whitespace. It checks balanced brackets.

Will formatting break my code?

Only whitespace changes in most cases. It is not a full parser, strings containing braces or semicolons may format incorrectly.

Does it parse TypeScript or JSX?

You can paste TS/JSX, but formatting is brace-based. Complex syntax may not layout perfectly.

What does Validate check?

It checks that curly braces, parentheses, and square brackets are balanced. A quick sanity check, not full syntax validation.
