Highlight any data range in the grid and seamlessly send it to your Antigravity AI Agent or VS Code Chat as a perfectly formatted Markdown table using a simple keyboard shortcut (Cmd + Shift + L).

  • High-Performance Data Grid: Powered by Web Workers and PapaParse, the viewer effortlessly handles large datasets without freezing your IDE. Say goodbye to legacy plugins and bloated extensions.
