One of the employees at my company is trying to publish some Excel files to our website (employee login only). The spreadsheet is rather large (12 columns wide), but there are no plans to convert it to dead-tree format; it's intended to stay digital. As such, the page layout is set to custom size landscape. When the spreadsheet is downloaded from our website, Excel opens it in protected view, which is expected since it's coming from a website. However, the protected view mode seems to be ignoring any page formatting, rendering it on 8.5x11 protrait pages, only allowing ~4 columns per page, and splitting it onto several horizontal pages.
I know that protected view is supposed to stop scripts etc from infecting computers, but is there any way to allow page formatting to be correctly displayed in protected view? I won't have access to every computer the file will be opened on, so default MS Office settings on the client-end would be preferred.
