Click it to instantly open a formatted JSON modal. Perfect for inspecting embedded JSON in logs, documentation, dashboards, or admin systems.

The selected theme applies consistently to both the settings popup and the JSON viewer modal. Real-Time Controls Enable or disable automatic detection and the selection tooltip independently. All changes apply instantly to the current page, no refresh required. Live Preview Preview how the JSON viewer will look with your current settings directly inside the extension popup.
