Opening and Viewing Office Documents with PSPDFKit for Web Standalone

You can load Office documents like you would any other file supported by PSPDFKit for Web. Use the load method, which takes a Configuration object as its parameter. This object specifies where the document is loaded on the page, the path to the source document, the license key, and more. For more information, see the guides on loading a document.

PSPDFKit.load({
  container: "#pspdfkit",
  document: "source.docx",
  licenseKey: "YOUR_LICENSE_KEY"
});
