Frequently Asked Questions
Does it create interfaces for nested objects?
Yes, it generates separate named interfaces for nested objects and infers array element types.
How are types inferred?
Types are inferred from the sample values in your JSON, mapping strings, numbers, booleans, arrays and objects to TypeScript types.
Is my JSON sent to a server?
No, the interfaces are generated locally in your browser so your JSON never leaves your device.
