機能

• Web Spreadsheet Editor (JavaScript, Angular, React, Vue, ASP.NET Core & MVC)
  • Threaded comments - To facilitate reviews, rich, threaded discussions are now supported on any cell. Users can reply, edit, delete, and resolve comments, with visual indicators for quick scanning. A dedicated review pane for navigation across threads, and JavaScript APIs help create, read, update, delete, and resolve comments while preserving thread state, author, and timestamps.
  • Notes in the ribbon - Lightweight, non-threaded notes can now be added and managed directly from the ribbon to capture quick annotations without starting a discussion. The features include options to insert notes, easily navigate between them, toggle their visibility for focused reviewing, and full JavaScript API support for integration and automation. Additionally, these notes are persistent in common load and save workflows.
• Blazor Spreadsheet Editor
  • Autofill series - Enables patterns and formats to be extended across cells horizontally or vertically, supporting sequences such as numbers, dates, and custom lists. It also allows copying versus filling series with preserved formatting, respecting selection direction, and maintaining cell formatting where applicable.
  • Merge cells - Adjacent cells can now be merged into a single cell to create headers, group related data, and produce organized worksheet layouts. This feature supports alignment and formatting operations, provides predictable validation for overlapping or partial selections, and offers APIs to merge or unmerge cells by selection, range address, or during import/export workflows.
  • Cell borders and grid lines - Custom borders can now be applied to cells or ranges to highlight sections, create table-like structures, and improve readability. This includes presets (outline, inside, and all borders), styles (line type, color, and thickness), and sheet-level grid line visibility toggles, all of which are available via the UI and APIs. Settings persist with the workbook and remain compatible with import and export operations.
• Visual Studio Extension
  • Syncfusion Spreadsheet Editor SDK Extension - The Spreadsheet Editor SDK Extension helps developers create applications for Blazor, WPF, or Windows Forms using the Syncfusion Spreadsheet Editor SDK components. For Blazor, a Spreadsheet Editor SDK code generator automatically inserts component code into Razor files while configuring namespaces, styles, and NuGet references. Additionally, developers can enhance existing WinForms or WPF projects by seamlessly integrating Spreadsheet Editor SDK components through intuitive item templates and reference manager options.
