JSON Bonsai

Prune, shape, and navigate giant JSON trees

JSON Bonsai turns any JSON page into a fast, interactive viewer — built to stay smooth even on 100,000+ node payloads where other viewers choke. FIVE VIEWS • Tree — virtualized rendering, collapsible nodes, depth controls (press 1–8 to set depth, 0 to expand all) • Table — sortable, virtualized rows for arrays of objects; works on query results too • Formatted — clean pretty-printed JSON • Raw — the original payload, untouched • Schema — an inferred JSON Schema (draft-07) QUERY, SEARCH & COPY • JMESPath query bar (Q) — filter and reshape the JSON; results render as a fully interactive tree • Content search in a web worker with match navigation (⌘F / ⌘G, Enter / Shift+Enter); in table view it filters rows • Hover any property to see its full JSON path — click to pin, then copy • Per-node actions — copy any subtree, expand/collapse all children • Copy JSON (C) — copies whatever the active view shows • Parsed payload available in the console as window.data FIDELITY • Lossless big numbers — 64-bit IDs and high-precision decimals display and copy exactly as sent, where JSON.parse would silently corrupt them PERSONALIZATION • base16 theming — 13 bundled schemes plus your own custom themes, with auto/dark/light switching • Per-site memory — your view mode and tree depth are remembered per origin and restored on your next visit Syntax highlighting for keys, strings, numbers, booleans and null. URLs become clickable links. Indent guides with hover highlighting. Open source, MIT licensed. No tracking, no data collection — the "storage" permission is used only to save your theme and per-site preferences locally.
