What is a JSON viewer and why do I need one?

A JSON viewer is a tool that displays JSON data in a structured, human-readable tree format instead of raw text. It makes it easy to explore deeply nested objects and arrays, find specific values, and understand the shape of your data. JSON viewers are essential when working with API responses, configuration files, and database exports.

Is my JSON data safe when using this viewer?

Yes, completely. This JSON viewer runs 100% in your browser using JavaScript. Your data never leaves your computer and nothing is sent to any server. You can safely paste API keys, tokens, or any sensitive data without privacy concerns.

Can this tool handle large JSON files?

Yes. The tree viewer is designed to handle large JSON documents efficiently. Nodes are collapsible so you can focus on the parts you need, and the search feature lets you find specific keys or values without manually scrolling through the entire structure. For very large files (over 10MB), performance may vary by browser.
