This conversion runs on our server to use a Node-only library. Your input is processed for the request and never stored.
TypeScript to JSON Schema is a free online converter on AltFTool that generates JSON Schema from TypeScript types and interfaces for validation workflows — no signup and nothing to install.
The conversion runs on AltFTool's server: your input is sent to the AltFTool API, written to a short-lived temporary file because ts-json-schema-generator reads from a path, and deleted as soon as the conversion finishes. It is not saved to an account or a database. TypeScript to JSON Schema is powered by the ts-json-schema-generator library, and the JSON Schema result can be copied or downloaded as typescript-to-json-schema.json.
The input is TypeScript source: the types, interfaces and declarations in what you paste are what the converter reads.

About 300ms after you stop typing, AltFTool posts your input to its conversion API and puts the JSON Schema output in the right-hand pane.
If this converter exposes options, open Settings to change them — the output re-runs as you adjust.
Copy the JSON Schema output with the Copy button, or download it as typescript-to-json-schema.json.
Yes — this one runs on the server. Your TypeScript is sent to the AltFTool API, written to a short-lived temporary file because ts-json-schema-generator reads from a file path, and deleted as soon as the conversion finishes. It is not saved to an account or a database.
The ts-json-schema-generator library, running on AltFTool's server. The JSON Schema you see is that library's output rather than an approximation written here.
Yes. Server-side converters accept up to 200,000 characters of input per request; anything larger is rejected with a "too large" error instead of being truncated.
The result is JSON Schema. Copy it from the output pane in one click, or download it as typescript-to-json-schema.json — AltFTool names the file after the converter and serves it as application/json.
Yes. TypeScript to JSON Schema is free to use on AltFTool, with no account and no sign-up.
