What is JSON Viewer?
A JSON viewer renders raw JSON as an organized, navigable structure so you can understand complex data at a glance. JSON Reader's viewer gives you three ways to look at the same data — an editable tree, an interactive node graph, and a sortable table — alongside a full code editor. It's ideal for inspecting API responses, config files, and large nested documents without losing your place.
