About JSON Schema Validator

JSONSchemaValidator.net is an interactive web page with two panes. You paste a schema in one and JSON input in the other, and it shows validation messages. You can start from an empty schema, a custom one, or the meta-schemas for each supported draft.

It supports JSON Schema Draft 3, 4, 6 and 7, 2019-09 and 2020-12. The site is built with Newtonsoft's Json.NET Schema library for C#, and the page shows the controller code used for validation.

Strengths

  • Supports JSON Schema drafts from 3 through 2020-12
  • Instant side-by-side schema and input editing
  • Built-in meta-schemas for each draft

Limitations

  • Validation is done on the server, so the data leaves your machine
  • Only validates; no schema generation or formatting
