Validators & Query

Validate and query data

Validate documents and query them without leaving the browser. Check JSON against a JSON Schema, verify YAML syntax before a deploy rejects it, test regular expressions live with capture groups, and run JSONPath or XPath expressions against real data. Errors come back with the path or line that failed, not a generic rejection.
