Document Solutions for PDF v8.2 添加與 OpenAI 的無縫 AI 集成,將非結構化 PDF 轉換為可用資料。

Document Solutions for PDF (DsPdf) by MESCIUS is a software development toolkit that provides .NET Core libraries and a JavaScript PDF viewer for manipulating and displaying PDFs. DsPdf enables developers to create, edit, annotate, and redact PDF documents directly within web applications. The included DsPdfViewer component offers a feature-rich, cross-platform solution for viewing and interacting with PDFs in modern browsers on various operating systems, including mobile devices.

The Document Solutions for PDF v8.2 update introduces a new AI-powered capability to extract tables from documents, enabling developers to convert unstructured tabular data in PDFs into structured, machine-readable formats with ease. By leveraging natural language prompts through OpenAI or Azure OpenAI services, this feature eliminates the need for manual parsing or coordinate-based extraction, reducing development effort. It provides reliable output even from PDFs with complex layouts or inconsistent formatting.

To see a full list of what's new in version 8.2, see our release notes.

Document Solutions for PDF is licensed per developer and is available in several license options for differing distribution needs. Team licenses are also available for multiple developers within the same organization. See our Document Solutions for PDF licensing page for full details.

新式試算表元件提供對列印和匯出的精確控制,從而保留跨格式的佈局、格式和資料完整性。

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.

在 ASP.NET Core 專案中實施支援螢幕閱讀器的圖表元件,可使資料視覺化供更廣泛的受眾使用。

Screen readers, in the context of charts, are assistive technologies that convert digital text and interface elements into speech or braille, allowing users with visual impairments to navigate and understand graphical data on the screen. This involves adding semantic structure, descriptive labels, and metadata so the chart's content can be understood through auditory feedback, enabling users with visual impairments to understand trends, values, and relationships within the chart without needing to see the visual representation. Proper implementation not only improves usability, particularly in data driven environments, but also supports compliance with established accessibility standards such as WCAG (Web Content Accessibility Guidelines).

Several ASP.NET Core charting components support the use of screen readers, such as:

  • ComponentOne Charts for ASP.NET MVC (part of ComponentOne Studio ASP.NET MVC by MESCIUS) follows WAI-ARIA accessibility guidelines and provides charts for ASP.NET Core.
  • Telerik ASP.NET Core Chart (part of Telerik UI for ASP.NET Core) uses inline SVG elements and supports assistive technologies, making chart data interpretable for screen readers.
  • jQWidgets ASP.NET Core MVC (part of jQWidgets) has built-in WAI-ARIA support and offers screen reader friendly charts for ASP.NET Core projects using Tag Helpers.
  • Infragistics ASP.NET Core Charts (part of Infragistics Professional) facilitates screen reader compatibility with comprehensive ARIA integration and text-based summaries.
