Frequently asked questions
Does it support TypeScript?+
Yes. The formatter handles TypeScript syntax including type annotations, interfaces, generics, and enums. It formats both .ts and .tsx code correctly.
Is my code sent to a server for formatting?+
No. All formatting runs in your browser. Your source code never leaves your device, so it is safe to format proprietary code, API keys in config, or any private files.
Does it support ES modules and modern syntax?+
Yes. It handles ES2024 syntax including optional chaining, nullish coalescing, top-level await, import assertions, and all modern JavaScript features.
Can I format minified JavaScript?+
Yes. Paste minified or obfuscated JavaScript and the formatter will add proper indentation and line breaks to make it human-readable again.
