Is JSON Viewer safe?

Yes, our JSON Viewer at jsonconsole.com/json-viewer is completely safe because all processing happens locally in your browser—your data never leaves your device or gets sent to any server. We do not store, transmit, or access your JSON data in any way. The viewer uses client-side JavaScript to parse and display JSON entirely within your browser session. This ensures complete privacy for sensitive data like API responses, configuration files, or personal information. When evaluating any JSON viewer, check if it processes data locally or sends it to servers. Browser-based tools that work offline are inherently safer. Our viewer requires no registration, account creation, or data collection. It is safe to use with confidential business data, personal projects, or sensitive information. For additional security, our site uses HTTPS encryption. The open-source nature of web technologies means you can inspect exactly what the viewer does, providing transparency and trust.
