JSON Dump

JSON Dump visualizes raw JSON as an interactive dump view inspired by cfdump. Open a saved .json file, an unsaved editor containing valid JSON, selected JSON text from any editor, or JSON straight from the clipboard and inspect nested data in a dedicated webview with collapsible tables and switchable key ordering.

Features

• Open saved .json files directly from Explorer.
• Open an active unsaved editor as soon as its contents are valid JSON; no save step required.
• Open selected JSON text from the current editor with JSON Dump: Selection.
• Open valid JSON from the clipboard with JSON Dump: Clipboard.
• Renders struct and arrays as nested tables.
• Collapse or expand nested structures from the header row or the key column.
• Toggle between natural key order and Sort Keys A->Z from the editor title while the dump panel is active.
• Keeps scalar values easy to scan with distinct colors for strings, numbers, booleans, and nulls.

Usage

1. Open a saved .json file from Explorer and run JSON Dump, or paste valid JSON into any editor tab and run JSON Dump from the editor title menu, editor title context menu, editor context menu, or the Command Palette.
2. To render only part of a document, select valid JSON text and run JSON Dump: Selection from the editor title context menu, the editor context menu, or the Command Palette.
3. To skip the editor entirely, copy valid JSON and run JSON Dump: Clipboard from the Command Palette, editor title context menu, or the editor context menu.
4. The viewer opens in a new tab.
5. Explore nested nodes in the webview, collapse or expand nodes by clicking their key columns or headers.
6. Use Sort Keys A->Z or Natural Key Order in the editor title while the dump panel is active.
