About:
JSON Viewer is a dedicated macOS application designed to parse, validate, and format JSON data with high performance. It transforms raw JSON strings into interactive, navigable tree structures, making complex datasets easy to understand. The tool serves as an essential utility for developers needing to quickly inspect API responses or local configuration files without using a web browser.

Key Features:

Interactive tree view for navigating nested JSON structures
Syntax highlighting and automatic formatting (pretty print)
Real-time validation with clear error highlighting
Support for large files and clipboard operations

Use Cases:

Inspecting and debugging JSON responses from REST APIs
Validating and formatting JSON configuration files for apps or DevOps tools

Alternatives:

jq – Command-line utility for slicing and filtering JSON output, whereas JSON Viewer provides a GUI for visual exploration.
Postman – Full API platform that includes JSON viewing, but JSON Viewer is a lightweight, standalone app focused solely on data visualization.
