Check a JSON payload against a Draft 7 schema before you send it to an API.
How to use JSON Schema Validator
- Paste your JSON or load the example.
- Select Validate against schema.
- Read the result in the output panel.
What the tool does
Paste a schema with rules such as required, type and properties. The result gives a path and message for each reported mismatch. This tool resolves local references within the schema. It leaves optional format checks, such as email and date-time, to the application.

Does my input leave this page?
The tool processes the input in your browser.
How much can I paste?
The input accepts up to one million characters.
Why is a large number rejected?
Numeric values outside the safe JavaScript integer range can lose digits. Put large identifiers in double quotes in JSON, or in single quotes in SQL.
What if the tool shows an error?
Check the error beneath the input. Load the example to see the format this tool expects.
