How to use JSON Schema Generator

Paste a sample JSON payload, and the tool infers the types and required fields to generate a matching JSON Schema document.

Frequently asked questions

Does it infer required fields correctly?

It marks every key present in your sample payload as required by default — remove any keys from the required array afterward that should actually be optional.

Can I use this file directly on my live site?

Yes, as a starting point — double-check paths, URLs, and directives against your actual domain before deploying.

Does this tool call any external API to generate the file?

No. Everything is built client-side in your browser from the values you enter.
