JSON Schema Generator
Infer a JSON Schema from a sample.
Schema from example data
Paste a representative JSON object and this infers a JSON Schema — types, properties, and nesting — so you have a starting contract for validation without writing it by hand.
It saves the tedious first draft of a validation contract, giving you a schema to tighten — marking fields required, adding formats and enums — rather than writing every property by hand.
A starting point
Tighten required fields and formats afterward, since one sample cannot show every rule. Generation runs entirely in your browser. Your sample is analysed on your device and never uploaded.
