Excel Cobrowsing


Glance Cobrowse supports cobrowsing Microsoft® Excel® files that your customer may wish to view when navigating your website. The following section outlines requirements and implementation steps for enabling cobrowsing of Excel files on your web property.

Supported File Types

  • .XLSX
  • .XLS
  • .CSV


While in a session, you can preview an Excel file using the Glance Visitor API. To launch the Excel viewer, call the Glance Visitor UI:

if(GLANCE.Cobrowse.Visitor.inSession() &&
   GLANCE.Cobrowse.Visitor.viewXLS) {
       GLANCE.Cobrowse.Visitor.viewXLS({url: "https://accounts.xlsx"})

Support for Binary Strings

NOTE: This functionality is available in Cobrowse 5.1 or later.

If you have Excel files that are passed from the server to the visitor's browser for download as binary strings, and there is no URL of the file to pass to the Glance viewPDF API call, you will need to call the following API:



  • You can only use the Excel viewer overlay on active sessions, and the cobrowse scripts must be loaded in the browser.
  • Excel Cobrowse is only available for Cobrowse version 4.17 and later.
  • This feature is not supported for visitors on Internet Explorer 11.
  • This feature is not supported for customers who self-host the Cobrowse script.

Cobrowsing Excel Files

  • The visitor sees the first sheet of the Excel file overlaid on their screen.
  • To navigate between sheets of the file, the visitor can use the arrow buttons in the top left.
  • The agent can scroll and gesture on the Excel file content.
  • The HTML representation of the Excel file looks like it does when viewed in the Excel application.
  • If sheets are too large (approximately 12k cells max), they will be truncated. The viewer displays in the header how many rows out of the total are being shown.
  • To exit, the visitor can click the X button, or refresh the page.
Excel cobrowse UI

NOTE: Pressing the back button will not navigate the visitor back to the page from which they launched the viewer. The Excel viewer functions like an overlay on the current page, not a new page.
