Add a schema and validate the JSON input.
What this validator checks
JSON syntax
Formatting and minifying use the browser JSON parser. Invalid commas, quotes, brackets, and values are reported without executing the input as code.
JSON Schema
The advanced tab checks structure and required properties using Ajv. Schema validation is separate from basic syntax validation.
Sorting keys
Sorting is optional because it changes the original property order. The underlying values are preserved.
