Install and Explore JSON Hero: A Powerful JSON Viewer

JSON Hero is a simple yet powerful JSON utility that offers a clean UI and extra features to make reading and understanding JSON documents easier and more intuitive.

It supports multiple views for inspecting JSON, such as column view, tree view, and raw JSON view; the column view is inspired by macOS Finder.

Project demo:

Content Preview

JSON Hero automatically infers the content of strings and provides useful previews and properties for selected values.

Date and Time

Image URL

Website URL

JSON URL

Tree View

This view is the most used; the tree structure clearly displays the data.

It also supports searching within JSON data.

When you finish editing or reviewing data, you can generate a shareable link instead of copying the entire dataset.

Overall, JSON Hero supports multiple views for JSON data, integrates with VS Code extensions, and is a handy tool for anyone who frequently works with JSON.
