JSON Prism

Opens JSON responses in Prism: tree, radial, graph, cards, schema, table, columns and raw views of one document.

JSON Prism turns any JSON response into an interactive explorer, right in the tab where it opened. Open an API response, a .json file or a raw GitHub link and, instead of a wall of text, you get eight linked views of the same document. Select a node in one view and it is selected in all of them. The inspector on the side always shows what the selection holds: its path, size, type breakdown and children. EIGHT VIEWS OF ONE DOCUMENT • Raw: syntax-highlighted source with folding, kept in sync with the selection • Tree: a collapsible, animated left-to-right hierarchy • Radial: the same hierarchy wrapped into a circle • Graph: a force-directed network of the whole document; long lists fold into +N nodes you can unfold • Cards: open objects one card at a time, linked by connectors • Schema: array items merged into one inferred shape, with types, presence % and value profiles for every field • Table: any array of objects as a sortable, filterable grid, with CSV export • Columns: Finder-style drill-down BUILT FOR REAL RESPONSES • Works on anything served as JSON (application/json, +json types, NDJSON / JSON Lines) • Detects JSON sent as plain text, such as raw.githubusercontent.com • Long arrays are paged, so large documents stay fast • Search keys and values with / or Ctrl+K • Copy a node's path or value, or download any object or array as a .json file • Switch to the browser's original view at any time, and back • Light and dark themes ALSO A STANDALONE VIEWER Click the toolbar button on any page to open Prism in its own tab. Paste JSON (validated as you type, with the line of any error), open or drag in a file, or fetch a URL. YOUR CHOICE OF HOW IT OPENS In settings, choose whether JSON pages open in Prism straight away or are left alone with a JSON badge on the toolbar button, turn plain-text detection on or off, and pick the first view a response opens in.
