Imprima y exporte hojas de cálculo con precisión

Agosto 26, 2025
Los componentes modernos de hojas de cálculo ofrecen un control preciso sobre la impresión y la exportación, preservando el diseño, el formato y la integridad de los datos en todos los formatos.

Spreadsheet components in modern UI frameworks offer robust capabilities for exporting and printing data, enabling users to take structured, interactive grid content and transform it into static or sharable formats. These features are crucial in enterprise applications, where end users often need to generate reports, export analysis results, or share datasets in widely recognized formats. Whether integrated into financial dashboards, inventory systems, or business intelligence tools, export and print functionalities ensure that grid data remains portable, consistent, and accessible across various workflows and platforms.

Common features include:

  • Exporting to CSV format allows for quick export of raw tabular data, preserving the structure of the spreadsheet while maintaining compatibility with most spreadsheet tools and data processing platforms.
  • Exporting to HTML provides a way to preserve the visual layout and styling of the spreadsheet for embedding in web-based documents or reports.
  • Exporting to JSON supports integration with APIs and back-end systems, making it easier to serialize grid data for programmatic use.
  • Exporting to Microsoft Excel (XSLX) retains advanced formatting, formulas, and multi-sheet structures, providing easy interoperability with the Excel desktop and web apps.
  • Image export captures a visual snapshot of the spreadsheet, useful for presentation slides or visual documentation where editable data is not required.
  • PDF export delivers a print-ready, paginated view of spreadsheet content with options for customizing headers, footers, fonts, and layout.
  • Printing support lets users generate hard copies or digital prints with configurable page settings, headers, and footers, often matching what is seen on screen.

Aplique funciones LAMBDA directamente a selecciones de celdas

Agosto 15, 2025
SpreadJS 18.2 agrega un nuevo comando Transform para ejecutar fórmulas LAMBDA sobre celdas seleccionadas y reemplazarlas en un solo paso.

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.

Las herramientas avanzadas a nivel de celda permiten a los usuarios ingresar, formatear y ajustar el contenido de las hojas de cálculo sin esfuerzo, combinando precisión con interacción intuitiva.

Cell-level editing and interaction features are essential components of any modern spreadsheet application, as they directly influence how users enter, modify, and manage data at the most granular level. These capabilities go beyond basic typing to provide enhanced flexibility, control, and context, enabling users to maintain accuracy while streamlining workflows. A well-designed set of cell-level tools supports both data integrity and user productivity, ensuring that spreadsheets can handle everything from quick updates to complex, structured datasets with efficiency and precision.

Common features include:

  • Cell Comments/Tooltips enable contextual notes or guidance to be attached to specific cells, aiding collaboration and documentation.
  • Cell Formatting provides options for adjusting fonts, colors, borders, and number formats, improving both readability and visual appeal.
  • Clipboard Operations such as cut, copy, and paste simplify moving or duplicating content while preserving formatting and formulas.
  • Find / Replace simplifies locating and updating values across large datasets.
  • In-cell Data Editing allows users to enter or update values directly within a cell for faster, more intuitive workflows.
  • Inserting Columns enables users to add new vertical sections to the spreadsheet, creating space for additional data fields or reorganizing existing content without overwriting adjacent information.
  • Inserting Images enables embedding of visual elements directly into the spreadsheet for richer presentations.
  • Inserting Rows allows the addition of new horizontal entries, supporting expansion of datasets, schedules, or tables while maintaining the integrity of surrounding data.
  • Merging Cells lets users combine multiple cells into one for clear headings or layout adjustments.
