JSON Viewer is a native Mac utility for opening, formatting, validating, and browsing JSON data in a fast local interface.
What is JSON Viewer?
JSON Viewer is a native macOS utility for working with JSON files and pasted JSON text. It helps developers, testers, and other technical users read structured data more comfortably by showing content with syntax highlighting and an expandable tree-style view. The app is designed for common tasks such as inspecting API responses, checking JSON syntax, and switching between compact and formatted output. It also supports navigating large datasets by expanding and collapsing nodes, which makes nested objects and arrays easier to follow. Because processing happens on the Mac, it fits offline workflows and everyday local data inspection. JSON Viewer is published by Pascal Giguère.

Safety overview
Status: Safe
This app’s file access is consistent with its purpose: you use it to open, read, and format JSON data on your Mac. For normal use, the main privacy consideration is the content you choose to load into it, especially if your JSON includes tokens, credentials, or other sensitive data. If you work with private datasets, keep copies secure and avoid sharing exported or reformatted content unintentionally.
Recommendation: Keep JSON Viewer if you regularly inspect or format JSON on your Mac. If you no longer use it, you can remove it like any other app without affecting macOS, though any app-specific settings or cached data may be removed with it.
