Ready. Your JSON stays in this browser.

How it works: Paste JSON, pick a language, and set a root name. Nested objects become their own types. Arrays of objects merge the item fields. A null value becomes optional when Nullable nulls is on.

Privacy: Conversion runs in your browser. Uploaded files are decoded locally with the encoding you choose and are not sent to a server.
