A developer-grade JSON exploration and diagnostic studio that parses payloads into structured in-memory trees, provides collapsible hierarchical node inspection, instant syntax error pinpointing with line/col pointers, live key/value search with highlighted matches, real-time structural metrics, and localStorage persistence.
- In-memory recursive tree rendering treating JSON strictly as structured data with collapsible nodes and path breadcrumbs
- Real-time syntax validator extracting exact error lines, columns, and rendering visual code pointers
- Live search engine querying across keys and values with auto-expansion of matched paths and active match navigation
- Real-time structural metrics computing object counts, array counts, property totals, and max nesting depth
- Formatted copy, minification, sample preset library, and snapshot history persisted in localStorage
Built with: Structured In-Memory Tree Parser, JSON Diagnostics & Error Pointer, Vanilla JavaScript, localStorage, CSS Grid / Flexbox, Developer Tools, Google Fonts (Sora, Outfit, Chivo Mono)
