About This App

JSON Viewer is a native macOS app designed to visualize, validate and format JSON datasets in a clean and responsive interface. It lets developers and data analysts read JSON with syntax highlighting, navigate through large datasets by expanding and collapsing tree nodes, and quickly switch between prettified and minified views. The app can handle large files offline, includes automatic error highlighting to spot invalid syntax, and supports a variety of colour schemes. It is aimed at developers, API testers, data engineers and anyone who regularly works with JSON files on macOS.

JSON Viewer is a native macOS app that already runs natively on Apple Silicon, so there is no migration step required. Your current installation will continue to work without any changes. If you are running an older version of JSON Viewer, you may want to check the vendor's website at jsonviewer.app to see if a newer build is available, which may include bug fixes or additional features — but even the older Intel-era versions of this app are actually native macOS builds and will not be affected by the removal of Rosetta 2 in macOS 28 (September 2028).
