Frequently asked questions

Does it create nested types?

Can I use this to design a schema?
Yes. It gives you a strong starting point that you can refine with arguments, scalars, and directives.
Is my data uploaded to a server?
No. Every tool on JSONPost runs entirely in your browser using JavaScript. Your JSON never leaves your device, so it is safe to use with private or sensitive data.
