Frequently Asked Questions
Is my JSON data sent to a server when I use this tool?
No. Formatting and validation happen entirely in your browser using JavaScript — your data is never transmitted anywhere, which matters if you're pasting in sensitive API responses or config files.
Can this tool detect JSON syntax errors?
Yes — invalid JSON is flagged with a description of the error so you can quickly locate and fix the problem.
