Installation – To run JSON Hero locally, clone the repository and install dependencies:

git clone https://github.com/jsonhero-io/jsonhero-web.git
cd jsonhero-web
npm install

Then start the application with:

Usage – Visit https://jsonhero.io/ , drag a JSON file onto the site or paste JSON/JSON URL into the form. The tool automatically infers string content and provides useful previews and attributes.

Views – The tree view displays JSON structures clearly; the column view (inspired by macOS Finder) offers a novel way to browse JSON; the raw JSON view shows the original text. Screenshots illustrate each view and the search functionality.
