A browser extension that allows you to select HTML table cells with mouse-dragging (exactly like in Microsoft Excel) and see instant calculations in a sleek status bar.

• Excel-style Selection: Drag your cursor over table cells to select a range.
• Instant Stats: Automatic calculation of Sum, Average, and Count for selected numeric values.
• Smart Copy (Ctrl+C): Copy selected cells as Tab-Separated Values (TSV), ready to be pasted directly into Excel or Google Sheets.
• Customizable:
  • Toggle extension on/off.
  • Theme support (Light, Dark, and System).
  • "Override Selection" mode to prevent default browser text behavior while selecting cells.
• Premium Design: Modern, glassmorphic status bar that appears dynamically.
