Secure JSON Viewer

About This Tool

Data security is a critical concern when processing JSON data that may contain API keys, user credentials, personal information, financial records, or proprietary business data. This Secure JSON Viewer is designed with security as the top priority: all processing runs 100% in your browser using JavaScript, with absolutely no data transmitted to any server. You can verify this by monitoring your browser's Network tab in DevTools — no requests are made when you process data. This architecture makes the tool suitable for processing classified, sensitive, or regulated data in environments where cloud-based tools are prohibited. Industries with strict data handling requirements (healthcare/HIPAA, finance/SOX, government/ITAR, legal/attorney-client privilege) can use this tool without compliance concerns.

What is JSON Viewer?

A JSON viewer provides a detailed structural analysis of JSON data, displaying every path from root to leaf nodes with the corresponding value and data type. Unlike a simple formatter that only adds indentation, a viewer deconstructs the JSON into a flat path representation (like $.users[0].name) that makes it easy to identify specific values within deeply nested structures. This is invaluable for understanding complex API responses, navigating large configuration objects, and building queries or transformations that target specific data paths. The viewer shows object key counts, array lengths, value types (string, number, boolean, null), and the full dot-notation path to every element.

How to Use This Tool

1. Paste your JSON.
2. Click Inspect JSON.
3. Browse paths, values, and types.
4. Use paths to reference data in your code.

Common Use Cases

• Processing sensitive JSON data (personal info, financial data)
• Working with proprietary API responses
• Handling JSON containing access tokens or credentials
• Privacy-compliant JSON processing for regulated industries
