Q: Does this validator support JSON with comments? A: Standard JSON does not support comments; this tool follows strict RFC 8259 specifications.
Q: Why is my JSON valid in my IDE but not here? A: Many IDEs permit non-standard features like trailing commas or single quotes which break strict JSON compliance.
Q: Can I validate JSON against a custom schema? A: Yes, the tool supports comparing your input against standard JSON Schema definitions for structural integrity.
