- Quick sheet switching even in large workbooks
- Smooth vertical and horizontal scrolling through thousands of rows
- Crisp rendering of tables, formulas, and cell formatting
- Supports spreadsheets that exceed typical mobile device limits
Thanks to advanced HTML5 and Ajax loading, even oversized datasets remain responsive.
