Características

• Web Spreadsheet Editor
  • Smart Spreadsheet:
    • Spreadsheet Editor includes a built-in AI Assist that lets users perform operations using natural language through a chat-based interface. With prompt suggestions and a resizable panel, users can efficiently interact with the Spreadsheet and take actions.
    • AI-powered actions, such as editing, formatting, data analysis, and visualization, are performed directly in the Spreadsheet with full undo and redo support. When a prompt is submitted, the AI service interprets the intent and applies the corresponding actions instantly, with results displayed in the UI and confirmed in the AI Assist panel.
  • Subscripts and superscripts - Subscript and superscript formatting enables the styling of specific portions of text within a cell. Directly format selected text during cell editing, enhancing clarity and improving the readability of complex data.
  • Suspend and resume UI refresh - Suspend and resume refresh API options improve UI rendering efficiency during bulk operations. Previously, the UI refreshed after every action, such as editing cells, which could impact performance when executing multiple operations in sequence. With this enhancement, UI updates can be temporarily paused using the suspendRefresh() method. Multiple programmatic changes can be performed efficiently, followed by a single refresh triggered with the resumeRefresh() method. This approach minimizes unnecessary re-rendering and significantly improves performance, especially during initialization, data processing, or large-scale updates.
• Blazor Spreadsheet Editor
  • Ribbon customization - Improved the spreadsheet experience with advanced ribbon customization. Add new tabs, create custom groups, and use tailored controls that align the interface with specific workflows. Existing tabs, groups, and items can be enhanced by inserting, rearranging, or removing elements while maintaining a consistent, intuitive user experience. These capabilities are supported by a simple, developer-friendly API that enables seamless configuration and integration.
  • Conditional formatting - Enhance data visualization by applying conditional formatting to selected ranges to highlight trends, outliers, and key values. Use color scales, data bars, and icon sets to deliver intuitive, engaging visuals, and ensure formatting updates dynamically as data changes to maintain accuracy.
  • Export to XLS, CSV, and PDF - Export spreadsheets in XLS, CSV, and PDF formats for seamless sharing and cross-platform compatibility while preserving data accuracy and formatting. PDF exports offer customizable layout options, including settings such as fitting the sheet onto a single page and adjusting orientation. These capabilities are available through both the UI and a simple, developer-friendly API.
  • Auto aggregation - Perform quick calculations in selected ranges using the spreadsheet footer's aggregation feature. It provides instant access to sums, averages, counts, and more without writing formulas. As data changes, results update automatically.
