Open MS Office Files in the Browser Using ASP.NET
Use JavaScript to open Word, Excel, and PowerPoint documents directly on any browser — no external dependencies or MS Office licenses required. Documents can be opened from a number of input sources, including remote URLs, blobs, array buffers, local storage, Base64 data, and more. The opened Office document can be displayed in the viewer or processed in a headless environment, where it can be annotated, edited, converted, and more. PSPDFKit for Web is fully compatible with ASP.NET.
PSPDFKit SDKs are deployed in some of the world’s most popular applications, such as those made by Autodesk, Disney, UBS, Dropbox, IBM, and Lufthansa.
