Frequently Asked Questions
What makes JSON invalid?
Common causes include missing or mismatched braces/brackets, missing quotes around keys, trailing commas after the last item in an array or object, and unescaped special characters.
Does it validate against a schema?
This tool validates the basic syntax of the JSON. For validating against a specific structure, you would need a JSON Schema validator.
Is there a limit to the nesting depth?
The validator can handle very deeply nested objects, though extremely deep structures may be limited by your browser's recursion limits.
