SpreadJS 19.1の強化デザイナーは、一貫したスタイルとフォーマットで事前設定済みのスプレッドシートテンプレートを最初から適用可能

SpreadJS is a JavaScript spreadsheet and data visualization component built to deliver Excel-compatible functionality within web applications. It provides a flexible, high-performance interface for displaying and manipulating tabular data, supporting advanced features such as formulas, pivot tables, charts, conditional formatting, and data binding. SpreadJS integrates smoothly with popular frameworks like React, Angular, and Vue, and includes robust import and export capabilities for Microsoft Excel files. It is commonly used in enterprise applications where users need a responsive, interactive spreadsheet experience directly in the browser.

The SpreadJS 19.1.0 update enhances the designer with a new templatesConfig option, allowing developers to define template configurations for new workbooks. By loading templates from remote sources or preloaded data, applications can apply consistent styles and formats during initialization or reset operations, helping teams standardize workbook creation and simplify spreadsheet setup.

To see a full list of what's new in 19.1.0, see our release notes.

SpreadJS is licensed per developer and includes 1 Year Maintenance (major and minor version releases and unlimited support phone calls). SpreadJS requires an Annual or Perpetual Deployment License. The optional Add-ons are available at an additional cost, and require a SpreadJS license. See our SpreadJS licensing page for full details.

Reactのスプレッドシートアプリケーションにインテリジェントな視覚的手がかりを追加し、ユーザーが傾向や閾値、重要な変更をより効率的に特定可能

Conditional formatting support in a React spreadsheet component allows developers to apply dynamic visual styling to cells based on defined rules, values, formulas where supported, or predefined conditions, such as highlighting trends, thresholds, errors, or status changes as data changes. This capability improves data readability and usability by helping users identify important information quickly without manual analysis, while also enabling more interactive and responsive data-driven applications. For software developers, it provides a familiar spreadsheet experience within React applications, reduces the need for custom rendering logic, and supports the creation of dashboards, financial tools, reporting systems, and enterprise data management interfaces with clearer visual context.

Several React spreadsheet controls support conditional formatting including:

  • SpreadJS by MESCIUS lets you apply rule-based conditional formatting in React spreadsheets, highlighting trends and thresholds with dynamic visual cell styling.
  • Infragistics Ignite UI for React Spreadsheet (part of Infragistics Ignite UI) allows you to create React spreadsheets using conditional formatting rules that emphasize critical data.
  • Syncfusion React Spreadsheet (part of Syncfusion Essential Studio Enterprise) facilitates conditional formatting enabling developers to visualize patterns and exceptions.
