The webinar includes the following key takeaways:

Use AI to generate and explain existing spreadsheet formulas.
Have AI generate PivotTables to give meaningful analysis to large datasets.
User AI within cells to do things like transition, gauge sentiment, and ask prompts based on spreadsheet data.

Watch the Webinar On-Demand and get ready to bring the power of AI to your JavaScript Spreadsheets.

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.

用日历控件确保可靠的日期输入

9月 2, 2025

JavaScript 日历控件为在基于 Web 的应用程序中管理日期选择提供了可靠且直观的解决方案。

JavaScript calendar controls are user interface components that allow users to select and edit date values directly within data editing environments, such as forms or grids. These controls typically integrate a visual calendar picker, enabling consistent and accurate date input while reducing manual entry errors. For developers, they simplify validation, support localization, and integrate with various data sources, helping ensure a more efficient and user-friendly experience in web applications that require date-related input or filtering.

Several JavaScript data editor collections offer calendar controls including:

DevExtreme Complete Data Editors (part of DevExteme Complete by DevExpress) lets you embed a calendar editor that maintains date-entry consistency in browser‑based apps.
KendoReact Data Editors (part of KendoReact by Telerik) allows integration of a responsive calendar for intuitive date selection, supporting customization and keyboard navigation.
Wijmo Input and Editors (part of Wijmo by MESCIUS) facilitates calendar‑based date editing within JavaScript UI inputs, ensuring accurate date selection across modern frameworks.
Infragistics Ignite UI for React Data Editors (part of Infragistics Ignite UI) facilitates the use of a built‑in calendar editor, enabling developers to deliver precise date input.

突出显示多个变量之间的关系

8月 29, 2025

多维图表揭示了多个指标或轴的模式和趋势，使其成为复杂数据分析的理想选择。

Multi-dimensional and relationship charts allow developers to present complex data structures and inter-variable relationships in a way that’s visually intuitive and analytically powerful. These chart types are essential for exploring correlations, comparing grouped metrics, and visualizing distributions across multiple dimensions. They are commonly used in statistical dashboards, performance analysis tools, and scientific applications where simple line or bar charts aren’t sufficient to capture the full context of the data.

Common charts include:

Combination Charts allow developers to overlay different chart types, such as bars, lines, and areas, within a single axis system, enabling comparison across metrics with varying scales or data types.
Radar & Polar Charts display multivariate data in a circular format, ideal for comparing values across categories that share a common center point, such as performance metrics or skill assessments.
Radial Chart formats extend circular visualization into more structured layouts, such as radial bar or radial line charts, providing a compact and distinctive way to show cyclical data or category-based trends.
Scatter & Bubble Charts plot data along two or three axes, often using the size of bubbles to represent an additional variable, making them ideal for visualizing trends, clusters, and outliers in high-volume datasets.

将 PDF 转换嵌入到 JavaScript 应用程序中

8月 27, 2025

在 JavaScript 应用程序中将 PDF 组件与转换支持集成允许用户在 PDF 和其它文件格式之间转换文档。

JavaScript PDF components that support format conversion play a critical role in modern web and enterprise applications, allowing developers to programmatically generate, manipulate, and transform documents within the browser or on the server. These tools simplify workflows that require format interoperability, such as generating printable reports from web content, archiving dynamic documents, or extracting data for analysis. Their ability to convert between PDF and other widely used formats ensures compatibility across systems, supports digital transformation goals, and enhances document handling efficiency.

Common conversions include:

HTML to PDF: Render entire web pages or fragments into paginated PDF documents while preserving layout, styles, and interactive elements.
PDF to Excel: Extract tabular data from PDFs, converting it into XLS or XLSX files for data analysis or re-use in spreadsheet applications.
PDF to Image: Convert each page of a PDF into image formats such as PNG or JPEG, useful for previews, thumbnails, or annotations.
RTF to PDF: Convert Rich Text Format files into PDFs to preserve text styling and document structure in a widely accepted format.
PDF to PowerPoint: Convert PDF content into PPT or PPTX format, enabling slide-based presentation of document content.
PDF to SVG: Translate PDF pages into scalable vector graphics, ideal for embedding high-quality visuals in web pages.
Word to PDF: Transform DOC or DOCX files into PDFs, retaining formatting, tables, and images for standardized sharing and storage.
