What is a TypeScript to JSON Schema Converter?
Convert TypeScript interfaces and type definitions directly to valid Draft-07 JSON Schema specifications. This tool re-indents and organizes code according to standard style conventions while checking for syntax validity. Everything executes 100% inside your browser, guaranteeing zero latency and complete privacy for API keys, user tokens, and confidential database schemas.
Frequently Asked Questions
How are optional properties handled?
Properties with `?` (e.g. `tags?: string[]`) are omitted from the JSON Schema `required` array, while non-optional properties are automatically included.
How are TypeScript string union literals converted?
Union literals (like `"admin" | "editor"`) are translated into JSON Schema `enum: ["admin", "editor"]` arrays.
Is my data uploaded when I use the TypeScript to JSON Schema Converter?
No. All processing runs entirely in your browser. Nothing is sent to a server unless you explicitly create a share link.
Does this tool work offline?
Yes. After the first visit, the PWA service worker can serve the page and run the formatter without a network connection.
What is the maximum input size?
Most tools accept up to about 5MB in the editor. Very large inputs are processed preferentially in a Web Worker and may download instead of filling the output pane.
