About this JSON tree viewer
Paste any JSON to render it as a collapsible tree: object and array nodes show their child count, the caret folds or unfolds each branch (the first two levels start expanded), every node carries a type badge and a $.a.b[0]-style access path, and leaf nodes show their value with one-click copy.
Keys, type badges and values are color-coded, long strings are truncated for display but copied in full, and Expand all / Collapse all switches between overview and detail. Invalid JSON produces a clear parse error. Everything is parsed locally — handy for inspecting API responses and config files.
