Product Introduction

Spire.WordJS.Blazor

A Blazor component for embedding Word document editing into your application. Set DocumentType to EditorType.Word and point DocumentUrl to a .doc or .docx file—users can immediately create, modify, and export Word documents with support for text formatting, images, tables, paragraphs, and page layouts, all through a native Blazor component interface.

Spire.ExcelJS.Blazor

A Blazor component that brings spreadsheet capabilities to your Web App. With DocumentType set to EditorType.Spreadsheet, users can view, edit, and calculate workbooks directly in the browser. Supports formulas, cell formatting, charts, and data validation—configured entirely through EditorSettings in C# without any JavaScript coding.

Spire.PresentationJS.Blazor

A Blazor component for editing and creating PowerPoint presentations within your application. Set DocumentType to EditorType.Presentation to enable support for text, graphics, and slide layouts. The component handles JavaScript interop internally, letting you work entirely in the Blazor programming model.

Spire.PDFJS.Blazor

A Blazor component for viewing PDF documents within your application. Set DocumentType to EditorType.Pdf and point DocumentUrl to a .pdf file to render documents with a lightweight viewing experience. Ideal for scenarios that require document review without full editing capabilities.
