JSON Viewer

Open JSON values from cells in two view modes: Text and Tree.

​
Open

  • Double-click a cell whose value parses as JSON, or
  • Click the chevron in a JSON-typed column.
The viewer opens as a popover anchored to the cell.

​
Modes

Switch with the segmented control in the viewer toolbar.
  • Text: syntax-highlighted JSON. Editable when the cell is editable. Use the {} button to format (pretty-print).
  • Tree: collapsible tree with a search field. Read-only navigation.
The default mode is set in Settings (Cmd+,) > Editor > JSON Viewer > Default view. If the document is too large to render as a tree, the tree mode shows an unavailability message and you stay in Text mode.

​
Open in Window

Click the pop-out button in the toolbar to detach the viewer into its own resizable window. Useful for large payloads or side-by-side reading. The window supports fullscreen.

​
Editing

In Text mode, edits are live in the binding. Click Save to commit the change through the standard change-tracking flow: the edit becomes a pending change in the data grid, previewed and applied via Save Changes. Click Cancel to drop the edit. If the edited text is not valid JSON when you save, the viewer prompts for confirmation before committing. See also: the JSON tab in the results status bar (Data / Structure / JSON) for whole-row JSON inspection.
