Frequently Asked Questions
Why isn't my JSON valid?
Common issues include trailing commas, single quotes instead of double, unquoted keys, or missing quotes around strings. The validator points to the exact error location.
Can I minify JSON?
Yes! Switch to minify mode to remove all whitespace and create compact JSON. Useful for reducing payload size in API responses and storage.
How do I navigate large JSON files?
Use tree view to expand and collapse sections. Click any value to copy its path. Search functionality helps find specific keys or values.
