JavaScript Formatter
Format and beautify JavaScript in your browser. Your code is not sent to Docspira.
Your JavaScript is formatted in this browser and is not sent to Docspira. It is never executed, evaluated, or imported; only reformatted as text. The formatter library itself is loaded as a pinned client-side script. Learn more.
Format JavaScript without running it
This tool re-indents JavaScript and makes it readable, including minified code. It supports modern syntax (let/const, arrow functions, classes, async/await, destructuring, optional chaining, nullish coalescing, template literals, modules). It does not deobfuscate code, lint, minify, transpile, or execute the JavaScript you submit.
What this tool does
Format JavaScript for easier reading and code review.
Before you start
This is a formatter, not a JavaScript runtime: pasted code is not executed in the page.
