DEVELOPER UTILITIES / LOCAL TOOL
JSON Schema Validator
Validate a JSON document against a local JSON Schema.
HOW IT WORKS
Validating JSON data against a schema
The validator compiles a JSON Schema 2020-12 document and checks the JSON instance against it entirely in the browser.
Limits to keep in mind
Remote $ref values are not fetched. Unknown formats are not treated as errors unless added to the schema’s validation logic.
A PRACTICAL WORKFLOW
Use the result carefully.
01Paste a JSON document and a JSON Schema. The validator uses the 2020-12 dialect and does not fetch remote references.
02Run the utility and inspect the complete output.
03Use a schema from a trusted specification and verify important data on the server that consumes it.
COMMON QUESTION
Does it send data to a schema registry?
