JSONView is a handy Chrome extension that transforms plain JSON documents into readable, well-formatted views directly in your browser. Instead of plain text, JSON files are highlighted and structured with collapsible arrays and objects for easy inspection. Even if a JSON contains errors, JSONView still displays the raw content, helping developers quickly understand the data. For a live demo, visit jsonview.com/example.json after installing the extension.

User reviews

Users appreciate JSONView as a free, simple, and effective extension that provides a clean and colorful JSON formatting experience, especially useful for developers. However, multiple users report significant limitations including failures with SharePoint 365 and OneDrive data, lack of support for REST APIs without .json URLs, sluggish performance on large JSON files, and compatibility problems on certain systems such as Mac Ventura and Microsoft setups.

Cons

Fails to work properly with SharePoint 365 / OneDrive causing errors or issues.
Does not work or fails to format JSON from REST APIs unless the URL ends with .json.
Performance issues with large JSON files causing long style loading times.
Does not work on some specific platforms like Mac Ventura or Microsoft-based setups.
