JSON Visor PRO is a Chrome extension designed for developers who frequently work with JSON data. It transforms raw JSON responses into a visually appealing and interactive tree format, featuring a modern Dracula theme that enhances readability. Key features include contextual search for keys and values, a summary mode to collapse array items for easier navigation, and a smart preview option that displays object content while collapsed. This tool significantly improves productivity when handling large JSON datasets.

In addition to its core functionalities, JSON Visor PRO offers optional features like a TypeScript generator, allowing users to convert JSON into ready-to-use TypeScript interfaces effortlessly. Users can also export data arrays directly to CSV for easy access in Excel. Notably, the extension ensures user privacy by processing data locally within the browser, without sending any JSON content to external servers.
