About this Tool
Use this free TypeScript Formatter to clean up interfaces, types, classes, functions, modules, components, and complete TypeScript source files. Paste compact or inconsistently formatted code, choose an indentation style, and generate a readable result while preserving annotations, generics, enums, access modifiers, decorators, and other TypeScript syntax. Processing runs locally in your browser and does not execute the source.
Examples
- interface User{id:number;name:string;active:boolean}const user:User={id:1,name:"Alice",active:true};
- type Status="pending"|"processing"|"complete";function updateStatus(status:Status):void{console.log(status)}
- class Product<T>{constructor(public id:T,public name:string,private price:number){}getPrice():number{return this.price}}
Frequently Asked Questions
Does the TypeScript Formatter remove type information?
No. Interfaces, annotations, generics, type aliases, enums, modifiers, and other TypeScript-specific syntax are preserved.
Does it compile TypeScript to JavaScript?
No. The tool formats TypeScript source code only. Compilation and type checking are separate operations.
Can the formatter process TSX?
It may support TSX when the parser and formatter engine are configured for JSX syntax. This should be exposed as an explicit mode when available.
Is my TypeScript uploaded?
No. TypeScript parsing and formatting run locally in your browser.
