I want to be able to edit an excel document that is attached to a Confluence page; open it, edit it, then save it directly back onto Confluence (without having to download and upload).
I've read that it is possible to click on the 'Edit File' button on an attachment, then click on 'Edit With'. When I click on 'Edit With' I'm left with a constant loading icon 
Is anyone aware of how I can solve this?
