FAQ

Does JSON Validator send my input to a backend API?

No. The current available BoxunBao tools run in the browser for normal processing and do not require an account or database write.

Can I use the output directly in production?

Review the output before using it in production systems. These tools help inspect, format, decode, or generate values, but they do not replace application-specific validation.

Where should I learn the workflow behind this tool?

Start with the related tutorial articles on this page, then use the tool to test examples or inspect the data format discussed in the guide.
