JSON Tree — Viewer & Export

Renders raw JSON as a collapsible tree, detected by content not Content-Type. Search, export to CSV/YAML/TS, JWT decode, diff.

**JSON Tree — Viewer & Export** turns any tab showing a raw JSON response into a readable tree: collapsible nodes, type highlighting, search, and click-to-copy JSONPath. The key difference from other JSON viewers: detection is based on **page content**, not the `Content-Type` header. Plenty of APIs serve JSON with `text/plain` or no content-type header at all — other viewers just show raw text in that case. This one doesn't care. **Features:** — Collapsible tree with syntax highlighting for strings/numbers/booleans/null — Search across keys and values, auto-expanding the right branches — Click any key to copy its JSONPath (`$.user.orders[2].id`) — Handles large JSON smoothly — content renders in chunks, no freezing — **Export** to CSV (a real table for arrays of records), YAML, or a TypeScript interface — **JWT decoder**: any string value shaped like a JWT gets an inline toggle that decodes header/payload as a tree; the popup also has a standalone decoder for any pasted token — **History**: recently viewed JSON pages are saved locally so you can jump back — **Diff tool** to compare two JSON documents by JSONPath — added/removed/changed, color-coded — Dark/light theme always follows the page's own setting — never leaks between tabs — Local `.json` files (`file://`) are supported too
