Office Opener

Modern browsers, such as Chrome, Firefox or the new Edge do not allow local contents to be linked from a site served over HTTP(S). This is a security feature, which though hinders some applications, like linking to local office files from a corporate intranet. This extension enables you to open Office files locally from a link. See below for more info

This only works with new versions of Microsoft Office!

What does it do

This Webextension enables you to open local Office Files directly from web/intranet pages. This was a functionality present in Internet Explorer and old Edge, but has since been removed from all major browsers.

How to use:

  • set a link on your web/intranet page to the file in the format file:///C:/path/to/the/file. Note the forward slashes
  • install the extension. It will turn all file-links which point to an Office file into Office-URL compatible links
  • click on the link. You should be prompted to select an application with which you want to open the file, choose the appropriate application.
