Step 1 - Get Started

Once the React doc viewer example is up and running, pass the URL, blob, file path, or arrayBuffer to initialDoc property in WebViewer constructor.

Code Example for React Document Viewer

WebViewer({
  ...,
  initialDoc: 'https://myserver.com/myfile.xlsx',
}, document.getElementById('viewer'));

You can also call loadDocument with the same parameters.

WebViewer(...)
  .then(instance => {
    instance.UI.loadDocument('https://myserver.com/myfile.xlsx', { filename: 'myfile.xlsx' });
  });

Step 2 - Run the App

You can now run the app via 'npm start'.

To view the npm React file viewer xlsx app, navigate to http://localhost:3000/. The app automatically reloads if you change any of the source files.
