Appliquez des fonctions LAMBDA directement aux sélections de cellules

Août 15, 2025
SpreadJS 18.2 ajoute une nouvelle commande Transformation pour exécuter des formules LAMBDA sur des cellules sélectionnées et les remplacer en une seule étape.

SpreadJS is a high-performance JavaScript spreadsheet and data presentation component designed for enterprise web applications. It enables developers to deliver Excel-like functionality directly within their web solutions, providing advanced features such as data binding, complex calculations, pivot tables, charts, and extensive formatting options. Fully compatible with modern JavaScript frameworks like React, Angular, and Vue, SpreadJS allows seamless integration and customization, empowering development teams to create interactive, data-driven user experiences without relying on external spreadsheet applications.

The SpreadJS 18.2 adds a new Transform command which enables you to apply LAMBDA functions directly to a selected range of cells and replace the original content with calculated results. This simplifies data transformations - whether mapping, filtering, or reshaping - into a clean, single-step process. With this feature, you can select any range and apply a custom LAMBDA formula - for example, converting units, adjusting values, or formatting entries - and have SpreadJS overwrite the selection with the computed results immediately. This removes manual steps like inserting formulas in separate cells, copying values, or pasting back as values. This feature integrates with SpreadJS’s existing LAMBDA capabilities to offer more interactive and efficient spreadsheet manipulation.

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.

Transformez les données d’une feuille de calcul en XML

Juillet 29, 2025
Les widgets de feuille de calcul .NET WinForms permettent d’exporter des données au format XML, ce qui garantit cohérence et portabilité pour un échange de données fiable.

Export to XML in a .NET WinForms Spreadsheet control allows developers to convert and save spreadsheet data into an XML (Extensible Markup Language) format, preserving the structure, content, and metadata of the spreadsheet in a standardized and portable form. This capability is particularly useful for integrating spreadsheet data with other systems, enabling data exchange, storage, or transformation. By using XML, the exported data can be consumed by a wide range of applications and platforms, making it easier to support interoperability and maintain consistency across different environments.

Several .NET 9 WinForms Spreadsheet controls offer Export to XML including:

  • Spread.NET WinForms by MESCIUS facilitates XML export of worksheet data, enabling integration with XML-based systems and workflows in a structured format.
  • DevExpress WinForms Spreadsheet (part of DevExpress WinForms) allows you to export spreadsheet content to XML, preserving data structure, formatting, and cell-level metadata for reuse.
  • Aspose.Cells for .NET lets you save spreadsheets as XML with full fidelity, supporting formulas, styles, and complex layout configurations.
