Large JSON DeskLarge JSON DeskOpen big JSON files (tested to 100 MB) in a fast, read-only, lazy-loading tree inside VS Code. Scanning runs in a worker thread; children load 500 at a time. Copy the JSONPath of any node ($.items[3].tags[1]). 100% offline: pure JavaScript, no telemetry, no network.

| Feature | Lite (free) | Pro (planned) |
|---|---|---|
| Read-only lazy tree, worker scan, paging | ✓ | ✓ |
| Key / type / preview, Copy JSONPath, status bar size + scan time | ✓ | ✓ |

Whole file held in memory (~2× size), so files above ~500 MB aren't supported yet. Rows stay rendered as you expand. Read-only by design.
