JSON Viewer by JsonForge.app

JSON Viewer by JsonForge.app turns the raw JSON page you get from navigating straight to an API endpoint into something actually readable — automatically, the moment the page loads. VIEWS • Pretty — a collapsible, syntax-highlighted tree • Table — arrays of objects normalized into a spreadsheet-style table, with CSV and Excel export • Relationship — a diagram showing how nested arrays link together as separate tables (parent/child, via _parentId) • Structure — infer TypeScript, Go, Python, PHP, Java, Kotlin, Rust, or C# type declarations from the JSON's shape • XML / YAML — the same data as XML or YAML, instantly HOW IT WORKS Open any URL that returns raw JSON (an API endpoint you navigate to directly) and the page is automatically replaced with the viewer — no clicking required. A "View original" toggle always gets you back to the raw text. Click the toolbar icon for a popup that works the same way with JSON you paste manually — handy for responses copied out of DevTools' Network tab. PRIVACY Everything runs locally in your browser. Nothing you view is collected, logged, or sent anywhere — see the full privacy policy linked below. Built by JsonForge.app, the team behind a free suite of browser-based JSON tools (formatter, table converter, diff, type generator, repair, and more) at jsonforge.app.
