JSON Schema Validator
Validate JSON values against simple JSON Schema object rules.
Input / Output
Start with the tool
Input, output, and copy actions stay in this main surface. Examples and reference checks are separated below.
Local session
Input state is saved only in this browser so you can restore the last workspace without an account.
Review after the result
Open examples, checks, and related tools only after the primary input/output flow is done.
Before copying
- Compare the output against the original input before copying.
- Remove secrets, customer data, and one-off environment values.
- Continue with json-formatter if the result needs another validation step.
Common failure cases
- JSON Schema Validator can still fail when the pasted input shape differs from {"type":"object","required":["id"]}.
- The output should be reviewed in the target data workflow before reuse.
