2026-07-30 09:04:36

E-iceblue today announced the official release of Spire.OfficeJS.Blazor, a native .NET Blazor component library designed for embedding in-browser Office document editing and PDF preview capabilities. With ready-to-use components and minimal setup, developers can seamlessly integrate Word, Excel, and PowerPoint editing alongside PDF viewing into Blazor Server, Blazor WebAssembly, or Blazor Web App projects — no manual JavaScript integration required.

Spire.OfficeJS.Blazor consists of four dedicated Blazor components : Spire.WordJS.Blazor, Spire.ExcelJS.Blazor, Spire.PresentationJS.Blazor, and Spire.PDFJS.Blazor. With a single DocumentType property, teams can seamlessly switch between Word, Excel, PowerPoint, and PDF workflows, accelerating development and eliminating the complexity of integrating multiple document engines.

Spire.WordJS.Blazor

A Blazor component for embedding Word document editing into applications. By setting DocumentType to EditorType.Word and pointing DocumentUrl to a .doc or .docx file, users can immediately create, modify, and export Word documents with full support for text formatting, images, tables, paragraphs, and page layouts.

Spire.ExcelJS.Blazor

A Blazor component that brings full spreadsheet capabilities to web applications. With DocumentType set to EditorType.Spreadsheet, users can view, edit, and calculate workbooks directly in the browser. It supports formulas, cell formatting, charts, and data validation.

Spire.PresentationJS.Blazor

A Blazor component for editing and creating PowerPoint presentations within applications. Set DocumentType to EditorType.Presentation to enable full support for text, graphics, and slide layout operations. The component handles JavaScript interop internally, allowing developers to work entirely within the standard Blazor programming model.

Spire.PDFJS.Blazor

A Blazor component for viewing PDF documents within applications. Set DocumentType to EditorType.Pdf and point DocumentUrl to a .pdf file to deliver a lightweight document viewing experience. It is ideal for document review scenarios that do not require full editing capabilities.
