Q: What is the difference between JSON and a JavaScript object? A: JSON is a data-interchange format with stricter rules, such as mandatory double quotes and no trailing commas.
Q: Can I validate against a JSON Schema? A: Yes, this tool allows you to provide a schema to ensure your JSON data follows a specific structure and data type requirement.
Q: Why does my JSON show as invalid with single quotes? A: The JSON specification (RFC 8259) requires double quotes for all strings and property names.
Q: How do I find the error in a large file? A: The validator provides line and column numbers; simply click the error message to jump directly to the issue.
