Frequently Asked Questions
Is my JSON data safe when using this JSON Viewer?
Yes, 100%. All processing and tree rendering happen entirely inside your local browser using client-side JavaScript. Zero data or files are uploaded to any external server.
How do I copy a specific JSON key path?
Simply click on any key or value node in the interactive tree view. The exact JSON path (e.g. $.users[0].address.city) will appear in the path bar, where you can click Copy Path to copy it instantly.
What happens if my JSON is invalid?
The tool automatically detects syntax errors, highlights the validation status in red, displays the exact parsing error message, and provides line and position details to help you fix it.
Can I view large JSON files offline?
Yes! Once loaded in your browser, the JSON Viewer works completely offline without requiring an active internet connection.
