I’ve added a new app to the Simple collection: JSONViewer.
It’s a native macOS app for viewing JSON files — think of it like Preview for images, but for .json files.
Features
JSONViewer is built with SwiftUI and includes:
- Syntax highlighting — color-coded keys, strings, numbers, booleans, and null values
- Expand/collapse — click the arrows to collapse objects and arrays
- Error detection — invalid JSON shows an error banner with the problematic line highlighted
- Copy to clipboard — one-click copy of the raw JSON
- Light/dark mode — follows your system theme
Like MarkdownViewer, it’s lightweight, focused, and just works.
