Q: Why is my JSON invalid if it works in my JavaScript code? A: JSON is a stricter subset of JavaScript; it requires double quotes for keys and forbids trailing commas.
Q: Does this tool store my JSON data? A: No, validation is processed via server actions and your input is not permanently stored or shared.
Q: Can I validate against a specific schema? A: Yes, the validator supports optional JSON Schema matching to ensure your data follows specific structural rules.
