About JSON Visualiser

JSON Visualiser replaces raw JSON pages with a clean interface built for reading and debugging. Instead of staring at unformatted text, you can inspect JSON in an editor, tree view, and graph view, validate structure instantly, and format content for easier analysis. It is useful when opening API responses, JSON files, and developer endpoints directly in the browser. The extension helps you understand nested objects faster, spot errors quickly, and work with large payloads more comfortably. Features include: - Automatic JSON page detection - Structured editor view - Expandable tree view - Graph visualisation for relationships - Real-time validation - Pretty print and formatting tools JSON Visualiser is designed for developers, QA engineers, data analysts, and anyone who works with JSON in the browser.
