Unminify TypeScript

Restore readable formatting from minified TS (alias beautify).

Basic example

Minified TypeScript

interface User{id:number;name:string}async function fetchUsers<T extends User>(ids:number[]):Promise<T[]>{const res=await fetch(`/api/users?ids=${ids.join(",")}`);return res.ok?(await res.json())?.data??[]:[]}

Formatted TypeScript

interface User { id: number; name: string; } async function fetchUsers<T extends User>(ids: number[]): Promise<T[]> { const res = await fetch(`/api/users?ids=${ids.join(',')}`); return res.ok ? ((await res.json())?.data ?? []) : []; }

Formatting options

Print width
Controls when Prettier wraps long lines — tighter for dense queries, wider for nested SDL.

Adjust tab width, tabs vs spaces, and quote style in the toolbar.

Prettier-powered formatting

Uses Prettier with the TypeScript parser. For JavaScript minification see our JS minifier or JS beautifier.

Local processing & data handling

Your TypeScript is parsed and reformatted in-browser with Prettier. No uploads, no server-side storage, and no account required — suitable for proprietary schemas, queries, and internal docs.
